TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars

Posted by klaurent MIT

Kavli Affiliate: Gabor Furesz | First 5 Authors: Ismael Mireles, Avi Shporer, Nolan Grieves, George Zhou, Maximilian N. Günther | Summary: We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exoplanet Survey Satellite (TESS). TOI 694 […]

Thermal Instability in the CGM of $L_{star}$ Galaxies: Testing “Precipitation” Models with the FIRE Simulations

Posted by klaurent Chicago

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Clarke J. Esmerian, Andrey V. Kravtsov, Zachary Hafen, Claude-Andre Faucher-Giguere, Eliot Quataert | Summary: We examine the thermodynamic state and cooling of the low-$z$ Circum-Galactic Medium (CGM) in five FIRE-2 galaxy formation simulations of Milky Way-mass galaxies. We find that the CGM in these simulations is […]
