Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis

Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31

The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…

Tidal Forcing on the Sun and the 11-year Solar Activity Cycle

Rodolfo G. Cionco, Sergey M. Kudryavtsev, Willie Soon

The hypothesis that tidal forces on the Sun are related to the modulations of the solar-activity cycle has gained increasing attention. The works proposing physical mechanisms of p…

Magnetic and Rotational Evolution of CrB from Asteroseismology with TESS

Travis S. Metcalfe, Jennifer L. van Saders, Sarbani Basu +15

During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent observations suggest th…

How much has the Sun influenced Northern Hemisphere temperature trends? An ongoing debate

Ronan Connolly, Willie Soon, Michael Connolly +20

To evaluate the role of Total Solar Irradiance (TSI) on Northern Hemisphere (NH) surface air temperature trends it is important to have reliable estimates of both quantities. 16 di…

The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS

Travis S. Metcalfe, Jennifer L. van Saders, Sarbani Basu +29

Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones from stellar evolutio…

Waldmeier Effect in Stellar Cycles

Suyog Garg, Bidya Binay Karak, Ricky Egeland +2

One of the most robust features of the solar magnetic cycle is that the stronger cycles rise faster than the weaker ones. This is popularly known as the Waldmeier Effect, which is…
