Impact of M-dwarf Stellar Wind and Photoevaporation on the Atmospheric Evolution of Small Planets
Ashini Modi, Raissa Estrela, Adriana Valio
The evolution of a planet's atmosphere depends strongly on its host star's properties. When their host stars are younger, planets can experience stronger winds and EUV emissions. T…
Dependence of stellar differential rotation on effective temperature and rotation: an analysis from starspot transit mapping
Araújo, Valio
Stellar rotation is crucial for studying stellar evolution since it provides information about age, angular momentum transfer, and magnetic fields of stars. In the case of the Sun,…
Statistical analysis of the onset temperature of solar flares in 2010-2011
Douglas Félix da Silva, Li Hui, Paulo J. A. Simões +7
Understanding the physical processes that trigger solar flares is paramount to help with forecasting space weather and mitigating the effects on our technological infrastructure. A…
Trajectories of Coronal Mass Ejection from Solar-type Stars
Fabian Menezes, Adriana Valio, Yuri Netto +3
The Sun and other solar-type stars have magnetic fields that permeate their interior and surface, extends through the interplanetary medium, and is the main driver of stellar activ…
The connection between starspots and superflares: a case study of two stars
Alexandre Araújo, Adriana Valio
How do the characteristics of starspots influence the triggering of stellar flares? Here we investigate the activity of two K-type stars, similar in every way from mass to rotation…
