JWST MEP - A World Under Spotty Starlight: Detection of CO2 and H2O in the Hot Saturn WASP-52b with JWST NIRSpec G395H
JWST GO 3969 Team, Yanbo Pan, Ryan J. MacDonald +21
Exoplanets orbiting active stars offer distinct challenges for atmospheric characterization with the JWST. Among such worlds, the hot Saturn WASP-52b (Teq 1300 K) orbits an…
A Multi-instrument Generalized Lomb-Scargle Periodogram Implementation
Giulia Martos, Néstor Espinoza, Jorge Meléndez
We present an implementation of the well-known and broadly used Generalized Lomb-Scargle Periodogram (GLS) which simultaneously takes into account individual offsets introduced in…
Hot Rocks Survey V: Secondary Eclipse Photometry of GJ 3473 b with JWST/MIRI
Måns Holmberg, Hannah Diamond-Lowe, João M. Mendonça +16
JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmo…
A distant brown dwarf coplanar to a warm Jupiter and a hot super-Earth
Matías I. Jones, Luca Naponiello, Trifon Trifonov +21
In transiting planetary systems, in which planetary sizes are accurately determined from transit observations, the presence of transit-timing variations (TTVs), especially when com…
A Warm Massive Pair of Planets around TOI-1232 Revealed with Transit-timing Variations and Doppler Spectroscopy
Deyan P. Mihaylov, Jan Eberhardt, Trifon Trifonov +32
TOI-1232 is a G-dwarf star with a mass of , a radius of , and slightly higher metallicity than solar of Fe/H = .…
JWST TRAPPIST-1 e/b Program: Motivation and first observations
Natalie H. Allen, Néstor Espinoza, V. A. Boehm +24
One of the forefront goals in the field of exoplanets is the detection of an atmosphere on a temperate terrestrial exoplanet, and among the best suited systems to do so is TRAPPIST…
JWST-TST DREAMS: Sulfur dioxide in the atmosphere of the Neptune-mass planet HAT-P-26 b from NIRSpec G395H transmission spectroscopy
Amélie Gressier, Natasha E. Batalha, Nicholas Wogan +24
We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with th…
JWST-TST DREAMS: NIRSpec/PRISM Transmission Spectroscopy of the Habitable Zone Planet TRAPPIST-1 e
Néstor Espinoza, Natalie H. Allen, Ana Glidden +32
TRAPPIST-1 e is one of the very few rocky exoplanets that is both amenable to atmospheric characterization and that resides in the habitable zone of its star -- located at a distan…
JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e
Ana Glidden, Sukrit Ranjan, Sara Seager +25
The TRAPPIST-1 system offers one of the best opportunities to characterize temperate terrestrial planets beyond our own solar system. Within the TRAPPIST-1 system, planet e stands…
Refractory and Volatile Species in the UV-to-IR Transmission Spectrum of Ultra-hot Jupiter WASP-178b with HST and JWST
Joshua D. Lothringer, Katherine A. Bennett, David K. Sing +17
The atmospheres of ultra-hot Jupiters are unique compared to other planets because of the presence of both refractory and volatile gaseous species, enabling a new lens to constrain…
JWST-TST DREAMS: A Precise Water Abundance for Hot Jupiter WASP-17b from the NIRISS SOSS Transmission Spectrum
Dana R. Louie, Elijah Mullens, Lili Alderson +27
Water has proven to be ubiquitously detected in near-infrared (NIR) transmission spectroscopy observations of hot Jupiter atmospheres, including WASP-17b. However, previous analyse…
Hints of a sulfur-rich atmosphere around the 1.6 R Super-Earth L98-59 d from JWST NIRSpec G395H transmission spectroscopy
Amélie Gressier, Néstor Espinoza, Natalie H. Allen +11
Detecting atmospheres around planets with a radius below 1.6 R, commonly referred to as rocky planets (Rogers_2015, Rogers_2021), has proven to be challenging. However,…
Atmospheric retrievals suggest the presence of a secondary atmosphere and possible sulfur species on L 98-59 d from JWST NIRSpec G395H transmission spectroscopy
Agnibha Banerjee, Joanna K. Barstow, Amélie Gressier +10
L 98-59 d is a Super-Earth planet orbiting an M-type star. We performed retrievals on the transmission spectrum of L 98-59 d obtained using NIRSpec G395H during a single transit, f…
Inhomogeneous terminators on the exoplanet WASP-39 b
Néstor Espinoza, Maria E. Steinrueck, James Kirk +40
Transmission spectroscopy has been a workhorse technique over the past two decades to constrain the physical and chemical properties of exoplanet atmospheres. One of its classical…
Latitudinal Asymmetry in the Dayside Atmosphere of WASP-43b
Ryan C. Challener, Zafar Rustamkulov, Elspeth K. H. Lee +9
We present two-dimensional near-infrared temperature maps of the canonical hot Jupiter WASP-43b using a phase-curve observation with JWST NIRSpec/G395H. From the white-light planet…
