Phase-modulated X-ray Emission from Cepheids due to Pulsation-Driven Shocks
Sofia-Paraskevi Moschou, Nektarios Vlahakis, Jeremy J. Drake +4
Cepheids are pulsating variable stars with a periodic chromospheric response at UV wavelengths close to their minimum radius phase. Recently, an X-ray variable signature was captur…
The Space Environment and Atmospheric Joule Heating of the Habitable Zone Exoplanet TOI700-d
O. Cohen, C. Garraffo, S. Moschou +4
We investigate the space environment conditions near the Earth-size planet TOI~700~d using a set of numerical models for the stellar corona and wind, the planetary magnetosphere, a…
Tuning the Exo-Space Weather Radio for Stellar Coronal Mass Ejections
Julián D. Alvarado-Gómez, Jeremy J. Drake, Federico Fraschetti +7
Coronal mass ejections (CMEs) on stars other than the Sun have proven very difficult to detect. One promising pathway lies in the detection of type II radio bursts. Their appearanc…
Investigating Opacity Modifications and Reaction Rate Uncertainties to Resolve the Cepheid Mass Discrepancy
Joyce A. Guzik, Ebraheem Farag, Jakub Ostrowski +4
Cepheid masses derived from pulsations or binary dynamics are generally lower than those derived from stellar evolution models. Recent efforts have been dedicated to investigating…
X-ray Observations of the Peculiar Cepheid V473 Lyr Identify A Low-Mass Companion
Nancy Remage Evans, Ignazio Pillitteri, Laszlo Molnar +17
V473 Lyr is a classical Cepheid which is unique in having substantial amplitude variations with a period of approximately 3.3 years, thought to be similar to the Blazhko variations…
(Simulating) Coronal Mass Ejections in Active Stars
Julián D. Alvarado-Gómez, Jeremy J. Drake, Cecilia Garraffo +4
The stellar magnetic field completely dominates the environment around late-type stars. It is responsible for driving the coronal high-energy radiation (e.g. EUV/X-rays), the devel…
