Hypotheses for Triton's Plumes: New Analyses and Future Remote Sensing Tests

Jason D. Hofgartner, Samuel P. D. Birch, Julie Castillo +14

At least two active plumes were observed on Neptune's moon Triton during the Voyager 2 flyby in 1989. Models for Triton's plumes have previously been grouped into five hypotheses,…

Recent formation and likely cometary activity of near-Earth asteroid pair 2019 PR2 -- 2019 QR6

Petr Fatka, Nicholas A. Moskovitz, Petr Pravec +13

Asteroid pairs are genetically related asteroids that recently separated (few million years), but still reside on similar heliocentric orbits. A few hundred of these systems hav…

Lunar-like silicate material forms the Earth quasisatellite (469219) 2016 HO3 Kamo`oalewa

Benjamin N. L. Sharkey, Vishnu Reddy, Renu Malhotra +7

Little is known about Earth quasi-satellites, a class of near-Earth small solar system bodies that orbit the sun but remain close to the Earth, because they are faint and difficult…

Volatile transport modeling on Triton with new observational constraints

T. Bertrand, E. Lellouch, B. J. Holler +18

Neptune's moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4 and CO, and represents a benchmark case for the study of surface-atmosphere interact…

EXPRES. III. Revealing the Stellar Activity Radial Velocity Signature of Eridani with Photometry and Interferometry

Rachael M. Roettenbacher, Samuel H. C. Cabot, Debra A. Fischer +20

The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) sh…

TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux

Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt +48

Mature super-Earths and sub-Neptunes are predicted to be Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15 planets around young stars even if t…
