TESS Hunt for Young and Maturing Exoplanets (THYME): a planet in the 45 Myr Tucana–Horologium association

ER Newton, AW Mann, BM Tofflemire… - The Astrophysical …, 2019 - iopscience.iop.org
Young exoplanets are snapshots of the planetary evolution process. Planets that orbit stars
in young associations are particularly important because the age of the planetary system is …

TESS Hunt for Young and Maturing Exoplanets (THYME). VI. An 11 Myr giant planet transiting a very-low-mass star in Lower Centaurus Crux

AW Mann, ML Wood, SP Schmidt… - The Astronomical …, 2022 - iopscience.iop.org
Mature super-Earths and sub-Neptunes are predicted to be≃ Jovian radius when younger
than 10 Myr. Thus, we expect to find 5–15 R⊕ planets around young stars even if their older …

TESS hunt for young and maturing exoplanets (THYME). II. A 17 Myr old transiting hot Jupiter in the Sco-cen association

AC Rizzuto, ER Newton, AW Mann… - The Astronomical …, 2020 - iopscience.iop.org
We present the discovery of a transiting hot Jupiter orbiting HIP 67522 (T eff∼ 5650 K; M*∼
1.2M⊙) in the 10–20 Myr old Sco-Cen OB association. We identified the transits in the TESS …

TESS hunt for young and maturing exoplanets (THYME). III. A two-planet system in the 400 Myr Ursa major group

AW Mann, MC Johnson, A Vanderburg… - The Astronomical …, 2020 - iopscience.iop.org
Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits,
and structures are shaped by their environment. Young planets (< 1 Gyr) offer an opportunity …

TESS Hunt for Young and Maturing Exoplanets (THYME). IV. Three Small Planets Orbiting a 120 Myr Old Star in the Pisces–Eridanus Stream

ER Newton, AW Mann, AL Kraus… - The Astronomical …, 2021 - iopscience.iop.org
Young exoplanets can offer insight into the evolution of planetary atmospheres,
compositions, and architectures. We present the discovery of the young planetary system …

ExoClock Project. II. A large-scale integrated study with 180 updated exoplanet ephemerides

A Kokori, A Tsiaras, B Edwards… - The Astrophysical …, 2022 - iopscience.iop.org
The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

The BAyesian STellar algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology

V Aguirre Børsen-Koch, JL Rørsted… - Monthly Notices of …, 2022 - academic.oup.com
We introduce the public version of the BAyesian STellar Algorithm (BASTA), an open-source
code written in Python to determine stellar properties based on a set of astrophysical …
