TESS Hunt for Young and Maturing Exoplanets (THYME) IX: a 27 Myr extended population of Lower-Centaurus Crux with a transiting two-planet system
Mackenna L. Wood, Andrew W. Mann, Madyson G. Barber +35
We report the discovery and characterization of a nearby (~ 85 pc), older (27 +/- 3 Myr), distributed stellar population near Lower-Centaurus-Crux (LCC), initially identified by se…
TESS observations of the Pleiades cluster: a nursery for delta Scuti stars
Timothy R. Bedding, Simon J. Murphy, Courtney Crawford +8
We studied 89 A- and F-type members of the Pleiades open cluster, including five escaped members. We measured projected rotational velocities (v sin i) for 49 stars and confirmed t…
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 Circumplanetary Dust Ring May Explain the Extreme Spectral Slope of the 10 Myr Young Exoplanet K2-33b
Kazumasa Ohno, Pa Chia Thao, Andrew W. Mann +1
Young exoplanets are attractive targets for atmospheric characterization to explore the early phase of planetary evolution and the surrounding environment. Recent observations of t…
HD 20329b: An ultra-short-period planet around a solar-type star found by TESS
F. Murgas, G. Nowak, T. Masseron +45
We used TESS light curves and HARPS-N spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate found around the star HD…
The TESS Grand Unified Hot Jupiter Survey. II. Twenty New Giant Planets
Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +83
NASA's Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited sample of transiting ho…
