Trajectory-Agnostic Asteroid Detection in TESS with Deep Learning
Brian P. Powell, Jorge Martinez-Palomera, Amy Tuson +3
We present a novel method for extracting moving objects from TESS data using machine learning. Our approach uses two stacked 3D U-Nets with skip connections, which we call a W-Net,…
TSSC comet-centered data products from TESS 3I/ATLAS observations
Jorge Martinez-Palomera, Amy Tuson, TESS Science Support Center
3I/ATLAS is the third known interstellar object to pass through our Solar System. NASA's Transiting Exoplanet Survey Satellite (TESS) made dedicated observations of 3I/ATLAS betwee…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Pre-discovery TESS Observations of Interstellar Object 3I/ATLAS
Jorge Martinez-Palomera, Amy Tuson, Christina Hedges +3
3I/ATLAS, also known as C2025 N1 (ATLAS), is the third known macroscopic interstellar object to pass through our Solar System. We report serendipitous Transiting Exoplanet Survey S…
A Swarm of WASP Planets: Nine giant planets identified by the WASP survey
Nicole Schanche, Guillaume Hébrard, Keivan G. Stassun +52
The Wide Angle Search for Planets (WASP) survey provided some of the first transiting hot Jupiter candidates. With the addition of the Transiting Exoplanet Survey Satellite (TESS),…
HIP 41378 observed by CHEOPS: Where is planet d?
S. Sulis, L. Borsato, S. Grouffal +84
HIP 41378 d is a long-period planet that has only been observed to transit twice, three years apart, with K2. According to stability considerations and a partial detection of the R…
Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815
Angelica Psaridi, Hugh Osborn, François Bouchy +130
We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906
Amy Tuson, Didier Queloz, Hugh P. Osborn +119
We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076
Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi +93
Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ( Myr) K-type star. Although a validated planetary system, th…
