Long-term X-ray Variability of the Symbiotic System RT Cru based on Chandra Spectroscopy
A. Danehkar, M. Karovska, J. J. Drake +1
RT Cru belongs to the rare class of hard X-ray emitting symbiotics, whose origin is not yet fully understood. In this work, we have conducted a detailed spectroscopic analysis of X…
Stellar Winds Drive Strong Variations in Exoplanet Evaporative Outflows and Transit Absorption Signatures
Laura M. Harbach, Sofia P. Moschou, Cecilia Garraffo +4
Stellar wind and photon radiation interactions with a planet can cause atmospheric depletion, which may have a potentially catastrophic impact on a planet's habitability. While the…
MESA models with magnetic braking
Seth Gossage, Aaron Dotter, Cecilia Garraffo +3
Two magnetic braking models are implemented in MESA for use in the MIST stellar model grids. Stars less than about 1.3 are observed to spin down over time through inter…
An Earth-like stellar wind environment for Proxima Centauri c
Julián D. Alvarado-Gómez, Jeremy J. Drake, Cecilia Garraffo +4
A new planet has been recently discovered around Proxima Centauri. With an orbital separation of au and a minimum mass of about , Proxima c is a prime…
The High-Energy Radiation Environment Around a 10 Gyr M Dwarf: Habitable at Last?
Kevin France, Girish Duvvuri, Hilary Egan +20
High levels of X-ray and UV activity on young M dwarfs may drive rapid atmospheric escape on temperate, terrestrial planets orbiting within the liquid water habitable zone. However…
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…
