GJ 238 b: A 0.57 Earth Radius Planet Orbiting an M2.5 Dwarf Star at 15.2 pc
Evan Tey, Avi Shporer, Zifan Lin +30
We report the discovery of the transiting planet GJ 238 b, with a radius of R ( times the radius of Mars) and an orbital period of 1.74 da…
Validation of a Third Planet in the LHS 1678 System
Michele L. Silverstein, Thomas Barclay, Joshua E. Schlieder +24
The nearby LHS 1678 (TOI-696) system contains two confirmed planets and a wide-orbit, likely-brown-dwarf companion, which orbit an M2 dwarf with a unique evolutionary history. The…
QLP Data Release Notes 003: GPU-based Transit Search
Michelle Kunimoto, Evan Tey, Willie Fong +3
The Quick-Look Pipeline (QLP; Huang et al. 2020, Kunimoto et al. 2021 and references therein) searches for transit signals in the multi-sector light curves of several hundreds of t…
Identifying Exoplanets with Deep Learning. V. Improved Light Curve Classification for TESS Full Frame Image Observations
Evan Tey, Dan Moldovan, Michelle Kunimoto +8
The TESS mission produces a large amount of time series data, only a small fraction of which contain detectable exoplanetary transit signals. Deep learning techniques such as neura…
TESS Discovery of Twin Planets near 2:1 Resonance around Early M-Dwarf TOI 4342
Evan Tey, Chelsea X. Huang, Michelle Kunimoto +28
With data from the Transiting Exoplanet Survey Satellite (TESS), we showcase improvements to the MIT Quick-Look Pipeline (QLP) through the discovery and validation of a multi-plane…
QLP Data Release Notes 002: Improved Detrending Algorithm
Michelle Kunimoto, Evan Tey, Willie Fong +2
Light curves feature many kinds of variability, including instrumental systematics, intrinsic stellar variability such as pulsations, and flux changes caused by transiting exoplane…
Quick-Look Pipeline Light Curves for 5.7 Million Stars Observed Over the Second Year of TESS' First Extended Mission
Michelle Kunimoto, Evan Tey, Willie Fong +5
We present High-Level Science Products (HLSPs) containing light curves from MIT's Quick-Look Pipeline (QLP) from the second year of TESS' first Extended Mission (Sectors 40 - 55; 2…
QLP Data Release Notes 001: K2 + TESS Analysis
Michelle Kunimoto, Chelsea Huang, Evan Tey +3
TESS will target the ecliptic plane in Sectors 42 - 46. These sectors overlap with campaigns from the K2 mission, providing a unique opportunity for multi-mission light curve analy…
Quick-Look Pipeline Lightcurves for 9.1 Million Stars Observed Over the First Year of the TESS Extended Mission
Michelle Kunimoto, Chelsea Huang, Evan Tey +7
We present a magnitude-limited set of lightcurves for stars observed over the TESS Extended Mission, as extracted from full-frame images (FFIs) by MIT's Quick-Look Pipeline (QLP).…
The LHS 1678 System: Two Earth-Sized Transiting Planets and an Astrometric Companion Orbiting an M Dwarf Near the Convective Boundary at 20 pc
Michele L. Silverstein, Joshua E. Schlieder, Thomas Barclay +48
We present the TESS discovery of the LHS 1678 (TOI-696) exoplanet system, comprised of two approximately Earth-sized transiting planets and a likely astrometric brown dwarf orbitin…
