KELT-11b is an inflated sub-Saturn with a hot atmosphere and that orbits a bright evolved subgiant star, making it a prime choice for atmospheric characterization, but that transit…
Understanding Accretion Variability Through TESS Observations of Taurus
Connor E. Robinson, Catherine C. Espaillat, Joseph E. Rodriguez
Interpreting the short-timescale variability of the accreting, young, low-mass stars known as Classical T Tauri stars remains an open task. Month-long, continuous light curves from…

First Doppler Limits on Binary Planets and Exomoons in the HR 8799 System
Andrew Vanderburg, Joseph E. Rodriguez
We place the first constraints on binary planets and exomoons from Doppler monitoring of directly imaged exoplanets. We model radial velocity observations of HR 8799 b, c, and d fr…
Mysterious Dust-emitting Object Orbiting TIC 400799224
Brian P. Powell, Veselin Kostov, Saul Rappaport +24
We report the discovery of a unique object of uncertain nature -- but quite possibly a disintegrating asteroid or minor planet -- orbiting one star of the widely separated binary T…
TIC 172900988: A Transiting Circumbinary Planet Detected in One Sector of TESS Data

We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star…
Two Massive Jupiters in Eccentric Orbits from the TESS Full Frame Images
Mma Ikwut-Ukwa, Joseph E. Rodriguez, Samuel N. Quinn +43
We report the discovery of two short-period massive giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS). Both systems, TOI-558 (TIC 207110080) and TOI-559 (TIC 2…
Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle
Maximilian N. Günther, David A. Berardo, Elsa Ducrot +37
New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 (scallop shells) and TESS (complex…
Tentative Evidence for Water Vapor in the Atmosphere of the Neptune-Size Exoplanet HD 106315 c
Laura Kreidberg, Paul Mollière, Ian J. M. Crossfield +27
We present a transmission spectrum for the Neptune-size exoplanet HD 106315 c from optical to infrared wavelengths based on transit observations from the Hubble Space Telescope/Wid…
The Hubble PanCET program: Transit and Eclipse Spectroscopy of the Strongly Irradiated Giant Exoplanet WASP-76b
Guangwei Fu, Drake Deming, Joshua Lothringer +21
Ultra-hot Jupiters with equilibrium temperature greater than 2000K are uniquely interesting targets as they provide us crucial insights into how atmospheres behave under extreme co…
Occultations from an active accretion disk in a 72 day detached post-Algol system detected by K2
G. Zhou, S. Rappaport, L. Nelson +28
Disks in binary systems can cause exotic eclipsing events. MWC 882 (BD-22 4376, EPIC 225300403) is such a disk-eclipsing system identified from observations during Campaign 11 of t…
