Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design

Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44

Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31

Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…

TESS Planet Occurrence Rates Reveal the Disappearance of the Radius Valley Around Mid-to-Late M Dwarfs

Erik Gillis, Ryan Cloutier, Emily Pass

We present the deepest systematic search for planets around mid-to-late M dwarfs to date. We have surveyed 8134 mid-to-late M dwarfs observed by TESS with a custom built pipeline a…

Pipeline for the Detection of Serendipitous Stellar Occultations by Kuiper Belt Objects with the Colibri Fast-Photometry Array

Emily Pass, Stanimir Metchev, Peter Brown +1

We report results from the preliminary trials of Colibri, a dedicated fast-photometry array for the detection of small Kuiper belt objects through serendipitous stellar occultation…

Kepler's Last Planet Discoveries: Two New Planets and One Single-Transit Candidate from K2 Campaign 19

Elyse Incha, Andrew Vanderburg, Tom Jacobs +9

The Kepler space telescope was responsible for the discovery of over 2,700 confirmed exoplanets, more than half of the total number of exoplanets known today. These discoveries too…

LHS 475 b: A Venus-sized Planet Orbiting a Nearby M Dwarf

Kristo Ment, David Charbonneau, Jonathan Irwin +10

Based on photometric observations by TESS, we present the discovery of a Venus-sized planet transiting LHS 475, an M3 dwarf located 12.5 pc from the Sun. The mass of the star is $0…

TOI-1846b: A super-Earth in the radius valley orbiting a nearby M dwarf

Abderahmane Soubkiou, Khalid Barkaoui, Zouhair Benkhaldoun +42

We present the discovery and validation of a super-Earth planet orbiting the M dwarf star TOI-1846 (TIC 198385543). The host star(Kmag = 9.6)is located 47 pc away and has a radius…

Brightest Cluster Galaxy Formation in the z=4.3 Protocluster SPT2349-56: Discovery of a Radio-Loud AGN

Scott C. Chapman, Ryley Hill, Manuel Aravena +29

We have observed the z=4.3 protocluster SPT2349-56 with ATCA with the aim of detecting radio-loud active galactic nuclei (AGN) amongst the ~30 submillimeter galaxies identified in…
