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 […]
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. […]
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 […]
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 […]
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 […]

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Tolga Guver, Tugba Boztepe, David R. Ballantyne, Z. Funda Bostanci, Peter Bult | Summary: We present spectral and temporal properties of all the thermonuclear X-ray bursts observed from Aql X-1 by the Neutron Star Interior and Composition Explorer (NICER) between 2017 July and 2021 April. This is […]
Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Saul Rappaport, Lorne Nelson, Donald W. Kurtz, George Dufresne | Summary: Using the novel TESS 20-sec cadence data, we have discovered an unusual combination of pulsating stars in what we infer to be a binary system. The primary is a standard $delta$ Scuti star with […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Ian Wong, Avi Shporer, George Zhou, Daniel Kitzmann, Thaddeus D. Komacek | Summary: We report the discovery of an ultrahot Jupiter with an extremely short orbital period of $0.67247414,pm,0.00000028$ days ($sim$16 hr). The $1.347 pm 0.047$ $R_{rm Jup}$ planet, initially identified by the Transiting Exoplanet Survey […]
Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Donald W. Kurtz, Gerald Handler, Saul Rappaport, George Ricker | Summary: We present two new rapidly oscillating Ap (roAp) stars, TIC 198781841 and TIC 229960986, discovered in TESS photometric data. The periodogram of TIC 198781841 has a large peak at 166.506 d$^{-1}$ (1.93 mHz), with […]
