A multi-wavelength look at the GJ 9827 system -- No evidence of extended atmospheres in GJ 9827 b and d from HST and CARMENES data
Ilaria Carleo, Allison Youngblood, Seth Redfield +18
GJ9827 is a bright star hosting a planetary system with three transiting planets. As a multi-planet system with planets that sprawl within the boundaries of the radius gap between…
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…
Reconstructing Extreme Space Weather from Planet Hosting Stars
V. S. Airapetian, V. Adibekyan, M. Ansdell +80
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…
The effect of Lyman radiation on mini-Neptune atmospheres around M stars: application to GJ 436b
Yamila Miguel, Lisa Kaltenegger, Jeffrey L. Linsky +1
Mini-Neptunes orbiting M stars are a growing population of known exoplanets. Some of them are located very close to their host star, receiving large amounts of UV radiation. Many M…
High Stellar FUV/NUV Ratio and Oxygen Contents in the Atmospheres of Potentially Habitable Planets
Feng Tian, Kevin France, Jeffrey L. Linsky +2
Recent observations of several planet-hosting M dwarfs show that most have FUV/NUV flux ratios 1000 times greater than that of the Sun. Here we show that the atmospheric oxygen con…
The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars
Kevin France, Cynthia S. Froning, Jeffrey L. Linsky +8
The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational o…
