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…
Spinning up a Daze: TESS Uncovers a Hot Jupiter orbiting the Rapid-Rotator TOI-778
Jake Clark, Brett Addison, Jack Okumura +68
NASA's Transiting Exoplanet Survey Satellite (TESS) mission, has been uncovering a growing number of exoplanets orbiting nearby, bright stars. Most exoplanets that have been discov…
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…
A sub-Neptune transiting the young field star HD 18599 at 40 pc
Jerome P. de Leon, John H. Livingston, James S. Jenkins +67
Transiting exoplanets orbiting young nearby stars are ideal laboratories for testing theories of planet formation and evolution. However, to date only a handful of stars with age <…
Three low-mass companions around aged stars discovered by TESS
Zitao Lin, Tianjun Gan, Sharon X. Wang +42
We report the discovery of three transiting low-mass companions to aged stars: a brown dwarf (TOI-2336b) and two objects near the hydrogen burning mass limit (TOI-1608b and TOI-252…
TESS discovery of a super-Earth and two sub-Neptunes orbiting the bright, nearby, Sun-like star HD 22946
Luca Cacciapuoti, Laura Inno, Giovanni Covone +51
We report the Transiting Exoplanet Survey Satellite (TESS) discovery of a three-planet system around the bright Sun-like star HD~22946(V=8.3 mag),also known as TIC~100990000, locat…
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…
HD 56414 b: A Warm Neptune Transiting an A-type Star
Steven Giacalone, Courtney D. Dressing, Antonio García Muñoz +17
We report the discovery in TESS data and validation of HD 56414 b (a.k.a. TOI-1228 b), a Neptune-size () planet with a 29-day orbital period t…
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…
Keck/NIRSPEC studies of He I in the atmospheres of two inflated hot gas giants orbiting K dwarfs: WASP-52b and WASP-177b
James Kirk, Leonardo A. Dos Santos, Mercedes López-Morales +5
We present the detection of neutral helium at 10833A in the atmosphere of WASP-52b and tentative evidence of helium in the atmosphere of the grazing WASP-177b, using high-resolutio…
The TESS Grand Unified Hot Jupiter Survey. I. Ten TESS Planets
Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +69
We report the discovery of ten short-period giant planets (TOI-2193A b, TOI-2207 b, TOI-2236 b, TOI-2421 b, TOI-2567 b, TOI-2570 b, TOI-3331 b, TOI-3540A b, TOI-3693 b, TOI-4137 b)…
