HD 191939 revisited: New and refined planet mass determinations, and a new planet in the habitable zone
J. Orell-Miquel, G. Nowak, F. Murgas +20
HD 191939 (TOI-1339) is a nearby (d=54pc), bright (V=9mag), and inactive Sun-like star (G9 V) known to host a multi-planet transiting system. Ground-based spectroscopic observation…
ACCESS: Tentative detection of HO in the ground-based optical transmission spectrum of the low-density hot Saturn HATS-5b
Natalie H. Allen, Néstor Espinoza, Andrés Jordán +13
We present a precise ground-based optical transmission spectrum of the hot-Saturn HATS-5b ( K), obtained as part of the ACCESS survey with the IMACS multi-object spec…
Identification of carbon dioxide in an exoplanet atmosphere
The JWST Transiting Exoplanet Community Early Release Science Team, Eva-Maria Ahrer, Lili Alderson +129
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (i.…
TOI-1468: A system of two transiting planets, a super-Earth and a mini-Neptune, on opposite sides of the radius valley
P. Chaturvedi, P. Bluhm, E. Nagel +67
We report the discovery and characterization of two small transiting planets orbiting the bright M3.0V star TOI-1468 (LSPM J0106+1913), whose transit signals were detected in the p…
ACCESS: Confirmation of a Clear Atmosphere for WASP-96b and a Comparison of Light Curve Detrending Techniques
Chima D. McGruder, Mercedes López-Morales, James Kirk +11
One of the strongest features was observed in WASP-96b. To confirm this novel detection, we provide a new 475-825nm transmission spectrum obtained with Magellan/IMACS,…
ATOCA: an algorithm to treat order contamination. Application to the NIRISS SOSS mode
Antoine Darveau-Bernier, Loïc Albert, Geert Jan Talens +20
After a successful launch, the James Webb Space Telescope is preparing to undertake one of its principal missions, the characterization of the atmospheres of exoplanets. The Single…
A detailed analysis of the Gl 486 planetary system
J. A. Caballero, E. Gonzalez-Alvarez, M. Brady +64
The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3 R_Terra and 3.0 M_Terra that…
The HD 260655 system: Two rocky worlds transiting a bright M dwarf at 10 pc
R. Luque, B. J. Fulton, M. Kunimoto +64
We report the discovery of a multi-planetary system transiting the M0 V dwarf HD 260655 (GJ 239, TOI-4599). The system consists of at least two transiting planets, namely HD 260655…
Empirical limb-darkening coefficients & transit parameters of known exoplanets from TESS
Jayshil A. Patel, Néstor Espinoza
Although the main goal of the Transiting Exoplanet Survey Satellite (\textit{TESS}) is to search for new transiting exoplanets, its data can also be used to study in further detail…
A transiting, temperate mini-Neptune orbiting the M dwarf TOI-1759 unveiled by TESS
Néstor Espinoza, Enric Pallé, Jonas Kemmer +66
We report the discovery and characterization of TOI-1759~b, a temperate (400 K) sub-Neptune-sized exoplanet orbiting the M~dwarf TOI-1759 (TIC 408636441). TOI-1759 b was observed b…
Discovery and mass measurement of the hot, transiting, Earth-sized planet GJ 3929 b
J. Kemmer, S. Dreizler, D. Kossakowski +64
We report the discovery of GJ 3929 b, a hot Earth-sized planet orbiting the nearby M3.5 V dwarf star, GJ 3929 (G 180--18, TOI-2013). Joint modelling of photometric observations fro…
The Effect of Stellar Contamination on Low-resolution Transmission Spectroscopy: Needs Identified by NASA's Exoplanet Exploration Program Study Analysis Group 21
Benjamin V. Rackham, Néstor Espinoza, Svetlana V. Berdyugina +58
Study Analysis Group 21 (SAG21) of NASA's Exoplanet Exploration Program Analysis Group (ExoPAG) was organized to study the effect of stellar contamination on space-based transmissi…
