The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- IV. Aperture Masking Interferometry
Anand Sivaramakrishnan, Peter Tuthill, James P. Lloyd +36
The James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph (JWST-NIRISS) flies a 7-hole non-redundant mask (NRM), the first such interferometer in space, opera…
Revisiting Radial Velocity Measurements of the K2-18 System with the Line-by-Line Framework
Michael Radica, Étienne Artigau, David Lafrenière +9
The cross-correlation function and template matching techniques have dominated the world of precision radial velocities for many years. Recently, a new technique, named line-by-lin…
Validation of TOI-1221 b: A warm sub-Neptune exhibiting TTVs around a Sun-like star
Christopher R. Mann, David Lafrenière, Diana Dragomir +25
We present a validation of the long-period ( days) transiting sub-Neptune planet TOI-1221 b (TIC 349095149.01) around a Sun-like (m=10.5)…
TOI-1452 b: SPIRou and TESS reveal a super-Earth in a temperate orbit transiting an M4 dwarf
Charles Cadieux, René Doyon, Mykhaylo Plotnykov +53
Exploring the properties of exoplanets near or inside the radius valley provides insights on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini…
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…
APPLESOSS: A Producer of ProfiLEs for SOSS. Application to the NIRISS SOSS Mode
Michael Radica, Loïc Albert, Jake Taylor +12
The SOSS mode of the NIRISS instrument is poised to be one of the workhorse modes for exoplanet atmosphere observations with the newly launched James Webb Space Telescope. One of t…
