A Blind Search for Transit Depth Variability with TESS
Gavin Wang, Néstor Espinoza
The phenomenon of transit depth variability offers a pathway through which processes such as exoplanet atmospheric activity and orbital dynamics can be studied. In this work we con…
Characterizing the Near-infrared Spectra of Flares from TRAPPIST-1 During JWST Transit Spectroscopy Observations
Ward S. Howard, Adam F. Kowalski, Laura Flagg +16
We present the first analysis of JWST near-infrared spectroscopy of stellar flares from TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6--2.8 m…
JWST-TST DREAMS: Quartz Clouds in the Atmosphere of WASP-17b
David Grant, Nikole K. Lewis, Hannah R. Wakeford +39
Clouds are prevalent in many of the exoplanet atmospheres that have been observed to date. For transiting exoplanets, we know if clouds are present because they mute spectral featu…
Atmospheric Reconnaissance of TRAPPIST-1 b with JWST/NIRISS: Evidence for Strong Stellar Contamination in the Transmission Spectra
Olivia Lim, Björn Benneke, René Doyon +22
TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting a Jupiter-sized M8.5V star, ideally suited for in-depth atmospheric studies. Each TRAPPIS…
Awesome SOSS: Transmission Spectroscopy of WASP-96b with NIRISS/SOSS
Michael Radica, Luis Welbanks, Néstor Espinoza +30
The future is now - after its long-awaited launch in December 2021, JWST began science operations in July 2022 and is already revolutionizing exoplanet astronomy. The Early Release…
The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- III. Single Object Slitless Spectroscopy
Loic Albert, David Lafreniere, Rene Doyon +37
The Near Infrared Imager and Slitless Spectrograph instrument (NIRISS) is the Canadian Space Agency (CSA) contribution to the suite of four science instruments of JWST. As one of t…
The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- I. Instrument Overview and in-Flight Performance
Rene Doyon, C. J Willott, John B. Hutchings +60
The Near-Infrared Imager and Slitless Spectrograph (NIRISS) is the science module of the Canadian-built Fine Guidance Sensor (FGS) onboard the James Webb Space Telescope (JWST). NI…
Awesome SOSS: Atmospheric Characterisation of WASP-96 b using the JWST Early Release Observations
Jake Taylor, Michael Radica, Luis Welbanks +13
The newly operational JWST offers the potential to study the atmospheres of distant worlds with precision that has not been achieved before. One of the first exoplanets observed by…
The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
In-orbit Performance of the Near-Infrared Spectrograph NIRSpec on the James Webb Space Telescope
T. Böker, T. L. Beck, S. M. Birkmann +47
The Near-Infrared Spectrograph (NIRSpec) is one of the four focal plane instruments on the James Webb Space Telescope. In this paper, we summarize the in-orbit performance of NIRSp…
