The TESS Faint Star Search: 1,617 TOIs from the TESS Primary Mission

Kavli Affiliate: George Ricker | First 5 Authors: Michelle Kunimoto, Tansu Daylan, Natalia Guerrero, William Fong, Steve Bryson | Summary: We present the detection of 1,617 new transiting planet candidates, identified in the Transiting Exoplanet Survey Satellite (TESS) full-frame images (FFIs) observed during the Primary Mission (Sectors 1 – 26). These candidates were initially detected […]

GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star

Kavli Affiliate: George R. Ricker | First 5 Authors: Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru, Xavier Bonfils, Davide Gandolfi | Summary: Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization […]

TOI-1842b: A Transiting Warm Saturn Undergoing Re-Inflation around an Evolving Subgiant

Kavli Affiliate: Avi Shporer | First 5 Authors: Robert A. Wittenmyer, Jake T. Clark, Trifon Trifonov, Brett C. Addison, Duncan J. Wright | Summary: The imminent launch of space telescopes designed to probe the atmospheres of exoplanets has prompted new efforts to prioritise the thousands of transiting planet candidates for follow-up characterisation. We report the […]

Constraints on the production of phosphine by Venusian volcanoes

Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Oliver Shorttle, Sukrit Ranjan, Paul B. Rimmer, Janusz J. Petkowski | Summary: The initial reports of the presence of phosphine in the cloud decks of Venus has led to the suggestion that volcanism was the source of phosphine, through volcanic phosphides ejected into the clouds. […]

H-alpha emission in local galaxies: star formation, time variability and the diffuse ionized gas

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Sandro Tacchella, Aaron Smith, Rahul Kannan, Federico Marinacci, Lars Hernquist | Summary: The nebular recombination line H$alpha$ is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H$alpha$ radiative transfer study of high-resolution isolated Milky-Way and Large Magellanic […]

The physics of Lyman-alpha escape from disc-like galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aaron Smith, Rahul Kannan, Sandro Tacchella, Mark Vogelsberger, Lars Hernquist | Summary: Hydrogen emission lines can provide extensive information about star-forming galaxies in both the local and high-redshift Universe. We present a detailed Lyman continuum (LyC), Lyman-alpha (Ly{alpha}), and Balmer line (H{alpha} and Hb{eta}) radiative transfer study […]

Sources of systematic error in gravitational-wave measurements of the binary neutron star mass distribution

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Colm Talbot, Salvatore Vitale, , | Summary: The binary neutron star (BNS) mass distribution measured with gravitational-wave observations has the potential to reveal information about the dense matter equation of state, supernova physics, the expansion rate of the universe, and tests of General Relativity. As […]
