Intense but Harmless: Exo-Space Weather Around an M Dwarf with a Single-Hemisphere Dynamo
Zheng Sun, Julián D. Alvarado-Gómez, Hui Tian +4
M dwarfs are among the most promising host stars in the search for habitable exoplanets. However, their active atmospheres drive intense magnetic activity, including energetic flar…
On Convective Turnover Times and Dynamos In Low-Mass Stars
Seth Gossage, Rocio Kiman, Kristina Monsch +7
The relationship between magnetic activity and Rossby number is one way through which stellar dynamos can be understood. Using measured rotation rates and X-ray to bolometric lumin…
The Magnetic Nature of the Cataclysmic Variable Period Gap
C. Garraffo, J. J. Drake, J. D. Alvarado-Gomez +2
One of the most important problems in the context of cataclysmic variables (CVs) is the lack of observations of systems with periods between 2 and 3.12 hours, known as the period g…
Simulating the environment around planet-hosting stars - II. Stellar winds and inner astrospheres
J. D. Alvarado-Gómez, G. A. J. Hussain, O. Cohen +4
We present the results of a comprehensive numerical simulation of the environment around three exoplanet-host stars (HD 1237, HD 22049, and HD 147513). Our simulations consider one…
Activity and Magnetic Field Structure of the Sun-Like Planet Hosting Star HD 1237
J. D. Alvarado-Gómez, G. A. J. Hussain, J. Grunhut +13
We analyse the magnetic activity characteristics of the planet hosting Sun-like star, HD 1237, using HARPS spectro-polarimetric time-series data. We find evidence of rotational mod…
