A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Fei Dai, Kevin C. Schlaufman, Henrique Reggiani, Luke Bouma, Andrew W. Howard | Summary: We report the discovery and Doppler mass measurement of a 7.4-day 2.3-$R_oplus$ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIRES spectrum, the Gaia parallax, and multi-wavelength […]

Applications of Deep Learning to physics workflows

Kavli Affiliate: George Ricker | First 5 Authors: Manan Agarwal, Jay Alameda, Jeroen Audenaert, Will Benoit, Damon Beveridge | Summary: Modern large-scale physics experiments create datasets with sizes and streaming rates that can exceed those from industry leaders such as Google Cloud and Netflix. Fully processing these datasets requires both sufficient compute power and efficient […]

Little Red Dots: an abundant population of faint AGN at $zsim5$ revealed by the EIGER and FRESCO JWST surveys

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Jorryt Matthee, Rohan P. Naidu, Gabriel Brammer, John Chisholm, Anna-Christina Eilers | Summary: Characterising the prevalence and properties of faint active galactic nuclei (AGN) in the early Universe is key for understanding the formation of supermassive black holes (SMBHs) and determining their role in cosmic reionization. […]

TOI-4010: A System of Three Large Short-Period Planets With a Massive Long-Period Companion

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Michelle Kunimoto, Andrew Vanderburg, Chelsea X. Huang, M. Ryleigh Davis, Laura Affer | Summary: We report the confirmation of three exoplanets transiting TOI-4010 (TIC-352682207), a metal-rich K dwarf observed by TESS in Sectors 24, 25, 52, and 58. We confirm these planets with HARPS-N radial velocity observations […]

Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard, Thomas Masseron, J. Lillo-Box | Summary: HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ($G=9.0$ mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of $3.9 pm 0.044$ $R_oplus$ (HIP 9618 […]

A Crystallizing White Dwarf in a Sirius-Like Quadruple System

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Simon Blouin, Antoine Bédard, Andrew Vanderburg, | Summary: The observational signature of core crystallization of white dwarfs has recently been discovered. However, the magnitude of the crystallization-powered cooling delay required to match observed white dwarfs is larger than predicted by conventional models, requiring additional mechanisms […]
