VLA detects possible extrasolar planetary-mass magnetic powerhouse

This was ‘the first radio detection and the first measurement of the magnetic field of a possible planetary mass object beyond our Solar System.’ It’s even bigger than Jupiter. Plenty of puzzles for scientists to investigate. Astronomers have used the VLA to detect a possible planetary-mass object with a surprisingly powerful magnetic field some 20 […]

Nature Print Edition Features Solar Planetary Theory

University of Montreal physicist Paul Charbonneau has written a short review of the Abreu et al paper published by ‘Astronomy and Astrophysics’, and featured on the talkshop last October. This is a good step forward for the hypothesis we have been working on here for the last three years, with important contributions from published scientists […]

Rudolf Wolf: Solar Planetary theorist! Who Knew?

Tucked in the footnotes to the Wolff and Patrone paper is a curious reference to an ‘Extract of a letter to Mr. Carrington.’ from none other than Rudolf Wolf (1816-1893), the famous solar observer and creator/curator of the best and most complete sunspot time series then in existence. The letter extract was printed in the […]

Study: How Planetary And Solar Oscillations Affect Earth’s Temperature Cycles

Introducing the term: Astronomical Harmonic Resonances (AHR). To see the figures cited below, go to the original article (here). A familiar topic to long-time Talkshop visitors, e.g. here. – – – The mechanism and even the existence of the Atlantic Multidecadal Oscillation (AMO) have remained under debate among climate researchers, and the same applies to […]

Solar-Planetary recap part one: The 11 year Schwabe cycle.

Now we’ve entered the minimum between solar cycles 24 and 25, this seems like a good moment to recap what we’ve discovered about the Sun and the planetary system that revolves around it here on the Talkshop during the last decade. The idea that the Sun’s activity cycles were somehow linked to the motion of […]

Zharkova uses solar-planetary theory in new paper predicting Earth temperature rise to 2600 following imminent Grand Solar Minimum

An important new solar paper by Prof Valentina Zharkova and co-authors S. J. Shepherd, S. I. Zharkov & E. Popova  published in ‘Nature’ has incorporated the solar-planetary theory we’ve been researching and advancing here at the talkshop over the last decade. As well as further developing her previous double dynamo theory which now accounts for the last several […]

Valentina Zharkova incorporates planetary theory into solar activity model

Last Wednesday I attended the talk by Professor Valentina Zharkova hosted by the GWPF in London. She delivered a superb lecture including news of new work improving her model by including quadrupole magnetic parameters. In the Q & A session that followed, I got the opportunity to point up the connection between her model output […]

Major breakthrough in solar-planetary theory: Barycentre research vindicated

As long time regulars at the Talkshop know, our ongoing research into the links between planetary motion and solar variation has occasionally borne fruit in unexpected ways. The ‘shorthand’ for the sum of all planetary vectors is the Sun’s motion with respect to the barycentre of the solar system. This is the path the Sun […]

Another dip into solar-planetary theory

This is an extended re-write of the earlier post on this topic. The purpose is to explain the Jose cycle chart shown below (in blue). – – – The Hale cycle is the time taken for solar magnetic polarity to return to its initial state (i.e. two ~11-year cycles: one north, one south), so the […]

A dip into solar-planetary theory

The details of interest here are: Jupiter’s orbit period (J): 11.862615 years Jupiter-Saturn conjunction period (J-S): 19.865036 years (mean value) Solar Hale cycle (HC): ~22.14 years (estimated mean value) Looking for a solar-planetary beat frequency (BF): 28 J = 332.15322 years 15 HC = 332.1 years 28 – 15 = 13 = number of beats […]

Gerry Pease Links Improved and Updated Solar -Planetary paper

Ex U.S. Naval Observatory astronomer and long-time talkshopper Gerry Pease has sent me a link to an update of the paper he wrote with Gregory Glenn which we discussed recently. It represents some important and novel work in our field of solar-planetary theory. Of particular interest is the tight phase and magnitude coherence of solar-barycentric torque […]

Blank sun provides more evidence for solar-planetary theory

The Sun usually exhibits ~11 year cycles of activity, but the historical sunspot record shows quite a large variance on this average figure. Here at the Talkshop, we have been developing a theory which relates solar activity levels to the motion of the planets, and in particular the motion of Jupiter, Earth and Venus. Simple indexes […]

Exoplanets’ complex orbital structure points to planetary migration in solar systems

As the report says: ‘Kepler-223’s two innermost planets are in a 4:3 resonance. The second and third are in a 3:2 resonance. And the third and fourth are in a 4:3 resonance.’ They are ‘far more massive than Earth’. Interesting to say the least. The four planets of the Kepler-223 star system seem to have […]

Empirical confirmation of solar-planetary theory: Solar polar field evolution matches 2011 prediction

Back in 2011. Tim Channon used his cycles analysis software to predict the evolution of the solar polar fields. The basis of the curve he produced is the motion of the gas giant planets, Jupiter, Saturn, Uranus and Neptune. As they orbit the Sun, they force the Sun to move relative to the centre of […]

Nicola Scafetta: Coherence between planetary, solar and climate oscillations: a reply to some critiques.

Nicola Scafetta has emailed me to let us know he has a new paper in press which adresses critiques of our solar-planetary theory. I can’t do justice to presenting this work by illustrating this post with figures from the paper using my cellphone, but this a seriously impressive piece of work which Nicola generously shares […]

McCracken Beer & Steinhilber: Evidence for Planetary Forcing of the Cosmic Ray Intensity and Solar Activity Throughout the Past 9400 Years

This is a major new paper published in the March issue of prestigious journal ‘Solar Physics’ by solar-planetary theorists Ken McCracken, Jurg Beer and Friedhelm Steinhilber, which makes a newer and more extensive analysis of planetary motion in relation to the Carbon 14 and Beryllium 10 Glactic cosmic ray proxies than the 2400 yr Hallstat […]

Nicola Scafetta and Richard Willson: New paper linking short term solar variation with planetary periods

Congratulations to Nicola Scafetta  and Richard Willson on the publication of their new paper, made freely available by high impact journal Pattern Recognition in Physics : Multiscale comparative spectral analysis of satellite total solar irradiance measurements from 2003 to 2013 reveals a planetary modulation of solar activity and its nonlinear dependence on the 11 yr […]

R.J. Salvador: Planetary model of 1000 yrs Solar Variation Plus 100yr Prediction

My thanks to R.J. Salvador for this guest posting of his solar variation model based on planetary periods. It’s forecast is in good agreement with that made by Tim Channon back in Feb 2011 using a different technique and different data (Judith Lean’s TSI reconstruction). R.J.’s model is available to interested parties known to the […]

Scafetta and Willson: Empirical evidences for a planetary modulation of total solar irradiance and the TSI signature of the 1.09-year Earth- Jupiter conjunction cycle

My Thanks to Nicola Scafetta for alerting us to his new paper co-authored with Richard Willson. The introductory section has a good condensed history of the solar-planetary theory worth a post in its own right really. But the meat of the paper deals with exciting new findings, including a finer resolution examination of the z-axis […]

Cameron and Schussler: No evidence for planetary influence on solar activity

My Thanks to Paul Vaughan for alerting me to a new paper which has appeared on ARXIV purporting to rebut Abreu et al’s 2012 paper  ‘Is there a planetary influence on solar activity?’. Paul has something to say about this paper, as well some other matters related. No evidence for planetary influence on solar activity […]
