Effects of the stellar wind on the Ly-alpha transit of close-in planets
S. Carolan, A. A. Vidotto, C. Villarreal D'Angelo +1
We use 3D hydrodynamics simulations followed by synthetic line profile calculations to examine the effect increasing the strength of the stellar wind has on observed Ly- transit…
Magnetic field and prominences of the young, solar-like, ultra-rapid rotator V530 Per
T. -Q. Cang, P. Petit, J. -F. Donati +7
We investigate signatures of magnetic fields and activity at the surface and in the prominence system of the ultra-rapid rotator V530 Per, a G-type solar-like member of the young o…
Influence of the Sun-like magnetic cycle on exoplanetary atmospheric escape
Gopal Hazra, Aline A. Vidotto, Carolina Villarreal D'Angelo
Stellar high-energy radiation (X-ray and extreme ultraviolet, XUV) drives atmospheric escape in close-in exoplanets. Given that stellar irradiation depends on the stellar magnetism…
The multi-planet system TOI-421 -- A warm Neptune and a super puffy mini-Neptune transiting a G9 V star in a visual binary
Ilaria Carleo, Davide Gandolfi, Oscar Barragán +110
We report the discovery of a warm Neptune and a hot sub-Neptune transiting TOI-421 (BD-14 1137, TIC 94986319), a bright (V=9.9) G9 dwarf star in a visual binary system observed by…
