Characterization of the visit-to-visit Stability of the GR700XD Wavelength Calibration for NIRISS/SOSS Observations
Tyler Baines, Néstor Espinoza, Joseph Filippazzo +1
When utilizing the NIRISS/SOSS mode on JWST, the pupil wheel (tasked with orienting the GR700XD grism into the optical path) does not consistently settle into its commanded positio…
Characterization of the visit-to-visit Stability of the GR700XD Spectral Traces for NIRISS/SOSS Observations
Tyler Baines, Néstor Espinoza, Joseph Filippazzo +1
In this report, we present the results of our analysis of trace position changes during NIRISS/SOSS observations. We examine the visit-to-visit impact of the GR700XD pupil wheel (P…
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…
Individual Dynamical Masses of DENIS J063001.4184014AB Reveal A Likely Young Brown Dwarf Triple
Johannes Sahlmann, Trent J. Dupuy, Adam J. Burgasser +6
The binary nature of the M8.5 dwarf DENIS J063001.4184014AB (DE063018) was discovered with astrometric monitoring from the ground, which determined the unresolved photocentri…
BANYAN. IX. The Initial Mass Function and Planetary-Mass Object Space Density of the TW Hya Association
Jonathan Gagné, Jacqueline K. Faherty, Eric E. Mamajek +15
A determination of the initial mass function (IMF) of the current, incomplete census of the 10 Myr-old TW Hya association (TWA) is presented. This census is built from a literature…
Discovery of a Substellar Companion to the Nearby Debris Disk Host HR 2562
Quinn M. Konopacky, Julien Rameau, Gaspard Duchene +54
We present the discovery of a brown dwarf companion to the debris disk host star HR 2562. This object, discovered with the Gemini Planet Imager (GPI), has a projected separation of…
