Hazy with a chance of star spots: constraining the atmosphere of the young planet, K2-33b
Pa Chia Thao, Andrew W. Mann, Peter Gao +10
Although all-sky surveys have led to the discovery of dozens of young planets, little is known about their atmospheres. Here, we present multi-wavelength transit data for the super…

A Population of Dipper Stars from the Transiting Exoplanet Survey Satellite Mission
Benjamin K. Capistrant, Melinda Soares-Furtado, Andrew Vanderburg +12
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10-50%, likely induced by occultations…
TESS spots a mini-neptune interior to a hot saturn in the TOI-2000 system
Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang +52
Hot jupiters (P < 10 d, M > 60 ) are almost always found alone around their stars, but four out of hundreds known have inner companion planets. These rare compan…
TIC 114936199: A Quadruple Star System with a 12-day Outer Orbit Eclipse

We report the discovery with TESS of a remarkable quadruple star system with a 2+1+1 configuration. The two unique characteristics of this system are that (i) the inner eclipsing b…
TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star
Alexis Heitzmann, George Zhou, Samuel N. Quinn +47
We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< Myr). This planet stands o…
Transit Hunt for Young and Maturing Exoplanets (THYME) VIII: a Pleiades-age association harboring two transiting planetary systems from Kepler
Madyson G. Barber, Andrew W. Mann, Jonathan L. Bush +8
Young planets provide a window into the early stages and evolution of planetary systems. Ideal planets for such research are in coeval associations, where the parent population can…
The Visual Survey Group: A Decade of Hunting Exoplanets and Unusual Stellar Events with Space-Based Telescopes
Martti H. K. Kristiansen, Saul A. Rappaport, Andrew M. Vanderburg +9
This article presents the history of the Visual Survey Group (VSG) - a Professional-Amateur (Pro-Am) collaboration within the field of astronomy working on data from several space…
The Discovery of a Planetary Companion Interior to Hot Jupiter WASP-132 b
Benjamin J. Hord, Knicole D. Colón, Travis A. Berger +21
Hot Jupiters are generally observed to lack close planetary companions, a trend that has been interpreted as evidence for high-eccentricity migration. We present the discovery and…
Another Shipment of Six Short-Period Giant Planets from TESS
Joseph E. Rodriguez, Samuel N. Quinn, Andrew Vanderburg +119
We present the discovery and characterization of six short-period, transiting giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS) -- TOI-1811 (TIC 376524552), TO…
Six New Compact Triply Eclipsing Triples Found With TESS

Reassessing the Evidence for Time Variability in the Atmosphere of the Exoplanet HAT-P-7 b
Maura Lally, Andrew Vanderburg
We reassess the claimed detection of variability in the atmosphere of the hot Jupiter HAT-P-7 b, reported by Armstrong et al. (2016). Although astronomers expect hot Jupiters to ha…
