TOI-2076 and TOI-1807: Two young, comoving planetary systems within 50 pc identified by TESS that are ideal candidates for further follow-up
Christina Hedges, Alex Hughes, Steven Giacalone +42
We report the discovery of two planetary systems around comoving stars; TOI-2076 (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multi-planetary system…
V1298 Tau with TESS: Updated Ephemerides, Radii, and Period Constraints from a Second Transit of V1298 Tau e
Adina D. Feinstein, Trevor J. David, Benjamin T. Montet +3
V1298 Tau is a young (20-30 Myr) solar-mass K star hosting four transiting exoplanets with sizes between 0.5 - 0.9 . Given the system's youth, it provides a unique opportunity…
An Aligned Orbit for the Young Planet V1298 Tau b
Marshall C. Johnson, Trevor J. David, Erik A. Petigura +22
The alignment of planetary orbits with respect to the stellar rotation preserves information on their dynamical histories. Measuring this angle for young planets help illuminate th…
A Search for Planetary Metastable Helium Absorption in the V1298 Tau System
Shreyas Vissapragada, Guðmundur Stefánsson, Michael Greklek-McKeon +28
Early in their lives, planets endure extreme amounts of ionizing radiation from their host stars. For planets with primordial hydrogen and helium-rich envelopes, this can lead to s…
H-alpha and Ca II Infrared Triplet Variations During a Transit of the 23 Myr Planet V1298 Tau c
Adina D. Feinstein, Benjamin T. Montet, Marshall C. Johnson +5
Young transiting exoplanets (< 100 Myr) provide crucial insight into atmospheric evolution via photoevaporation. However, transmission spectroscopy measurements to determine atmosp…
exoplanet: Gradient-based probabilistic inference for exoplanet data & other astronomical time series
Daniel Foreman-Mackey, Rodrigo Luger, Eric Agol +13
"exoplanet" is a toolkit for probabilistic modeling of astronomical time series data, with a focus on observations of exoplanets, using PyMC3 (Salvatier et al., 2016). PyMC3 is a f…
