Peakbagging the K2 KEYSTONE sample with PBjam: characterising the individual mode frequencies in solar-like oscillators

George T. Hookway, Martin B. Nielsen, Guy R. Davies +5

The pattern of individual mode frequencies in solar-like oscillators provides valuable insight into their properties and interior structures. The identification and characterisatio…

Modelling the effect of stellar metallicity on the XUV evolution of low-mass stars and its impact on exoplanet atmospheres/habitability

Victor See, Charlotte Fairman, Louis Amard +1

Understanding how exoplanet atmospheres evolve is a key question in the context of habitability. One key process governing this evolution is atmospheric evaporation by stellar X-ra…

Weakened Magnetic Braking Signals the Collapse of the Global Stellar Dynamo

Travis S. Metcalfe, Jennifer L. van Saders, Marc H. Pinsonneault +7

Weakened magnetic braking (WMB) was originally proposed in 2016 to explain anomalously rapid rotation in old field stars observed by the Kepler mission. The proximate cause was sug…

The magnetic and spin-down properties of slowly rotating fully convective M dwarfs

Victor See, Louis Amard, Stefano Bellotti +19

The evolution of the magnetism, winds and rotation of low-mass stars are all linked. One of the most common ways to probe the magnetic properties of low-mass stars is with the Zeem…

Testing the Rossby Paradigm: Weakened Magnetic Braking in early K-type Stars

Travis S. Metcalfe, Pascal Petit, Jennifer L. van Saders +12

There is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds…

A BCool survey of stellar magnetic cycles

S. Bellotti, P. Petit, S. V. Jeffers +6

The magnetic cycle on the Sun consists of two consecutive 11-yr sunspot cycles and exhibits a polarity reversal around sunspot maximum. Although solar dynamo theories have progress…
