TESS light curves of low-mass detached eclipsing binaries
Krzysztof G. Hełminiak, Andrés Jordán, Nestor Espinoza +1
We present high-precision light curves of several M- and K-type, active detached eclipsing binaries (DEBs), recorded with 2-minute cadence by the Transiting Exoplanet Survey Satell…
TOI-677 b: A Warm Jupiter (P=11.2d) on an eccentric orbit transiting a late F-type star
Andrés Jordán, Rafael Brahm, Néstor Espinoza +46
We report the discovery of TOI-677 b, first identified as a candidate in light curves obtained within Sectors 9 and 10 of the Transiting Exoplanet Survey Satellite (TESS) mission a…
ACCESS: A Visual to Near-infrared Spectrum of the Hot Jupiter WASP-43b with Evidence of , but no evidence of Na or K
Ian C. Weaver, Mercedes López-Morales, Néstor Espinoza +11
We present a new ground-based visual transmission spectrum of the hot Jupiter WASP-43b, obtained as part of the ACCESS Survey. The spectrum was derived from four transits observed…
K2-19b and c are in a 3:2 Commensurability but out of Resonance: A Challenge to Planet Assembly by Convergent Migration
Erik A. Petigura, John Livingston, Konstantin Batygin +11
K2-19b and c were among the first planets discovered by NASA's K2 mission and together stand in stark contrast with the physical and orbital properties of the solar system planets.…
TOI-222: a single-transit TESS candidate revealed to be a 34-day eclipsing binary with CORALIE, EulerCam and NGTS
Monika Lendl, François Bouchy, Samuel Gill +58
We report the period, eccentricity, and mass determination for the TESS single-transit event candidate TOI-222, which displayed a single 3000 ppm transit in the TESS two-minute cad…
The highly inflated giant planet WASP-174b
L. Mancini, P. Sarkis, Th. Henning +18
The transiting exoplanetary system WASP-174 was reported to be composed by a main-sequence F star (V=11.8 mag) and a giant planet, WASP-174b (orbital period 4.23 days). However onl…
LRG-BEASTS: transmission spectroscopy and retrieval analysis of the highly-inflated Saturn-mass planet WASP-39b
James Kirk, Mercedes Lopez-Morales, Peter J. Wheatley +5
We present a ground-based transmission spectrum and comprehensive retrieval analysis of the highly inflated Saturn-mass planet WASP-39b. We obtained low-resolution spectra ($R \app…
Estimation of singly-transiting K2 planet periods with Gaia parallaxes
Emily Sandford, Néstor Espinoza, Rafael Brahm +1
When a planet is only observed to transit once, direct measurement of its period is impossible. It is possible, however, to constrain the periods of single transiters, and this is…
The Habitability of GJ 357 d : Possible Climates and Observability
L. Kaltenegger, J. Madden, Z. Lin +5
The GJ 357 system harbors 3 planets orbiting a bright, nearby M2.5V star at 9.44pc. The innermost planet GJ 357 b (TOI-562.01) is a hot transiting Earth-size planet with Earth-like…
Two new HATNet hot Jupiters around A stars, and the first glimpse at the occurrence rate of hot Jupiters from TESS
G. Zhou, C. X. Huang, G. Á. Bakos +68
Wide field surveys for transiting planets are well suited to searching diverse stellar populations, enabling a better understanding of the link between the properties of planets an…
TOI-150b and TOI-163b: two transiting hot Jupiters, one eccentric and one inflated, revealed by TESS near and at the edge of the JWST CVZ
Diana Kossakowski, Néstor Espinoza, Rafael Brahm +51
We present the discovery of TYC9191-519-1b (TOI-150b, TIC 271893367) and HD271181b (TOI-163b, TIC 179317684), two hot Jupiters initially detected using 30-minute cadence Transiting…
Constraining Stellar Photospheres as an Essential Step for Transmission Spectroscopy of Small Exoplanets
Benjamin V. Rackham, Arazi Pinhas, Dániel Apai +29
Transmission spectra probe the atmospheres of transiting exoplanets, but these observations are also subject to signals introduced by magnetic active regions on host stars. Here we…
HD 213885b: A transiting 1-day-period super-Earth with an Earth-like composition around a bright () star unveiled by TESS
Néstor Espinoza, Rafael Brahm, Thomas Henning +60
We report the discovery of the 1.008-day, ultra-short period (USP) super-Earth HD 213885b (TOI-141b) orbiting the bright () star HD 213885 (TOI-141, TIC 403224672), detected…
A discontinuity in the -radius relation of M-dwarfs
Markus Rabus, Régis Lachaume, Andrés Jordán +7
We report on 13 new high-precision measurements of stellar diameters for low-mass dwarfs obtained by means of near-infrared long-baseline interferometry with PIONIER at the Very La…
Ephemeris refinement of 21 Hot Jupiter exoplanets with high timing uncertainties
M. Mallonn, C. von Essen, E. Herrero +32
Transit events of extrasolar planets offer a wealth of information for planetary characterization. However, for many known targets, the uncertainty of their predicted transit windo…
