Early science with SPIRou: near-infrared radial velocity and spectropolarimetry of the planet-hosting star HD 189733
Claire Moutou, Shweta Dalal, Jean-Francois Donati +16
SPIRou is the newest spectropolarimeter and high-precision velocimeter that has recently been installed at the Canada-France-Hawaii Telescope on Maunakea, Hawaii. It operates in th…
Masses, Revised Radii, and a Third Planet Candidate in the "Inverted" Planetary System Around TOI-1266
Ryan Cloutier, Michael Greklek-McKeon, Serena Wurmser +40
Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or is it a direct outcome of the planet formation process? A number of recent empirical…
Chromaticity of stellar activity in radial velocities : Anti-correlated families of lines on the M dwarf EV Lac with SPIRou and SOPHIE
Pierre Larue, Xavier Delfosse, Andres Carmona +33
Context. In the search for exoplanets using radial velocities (RV), stellar activity has become one of the main limiting factors for detectability. Fortunately, activity-induced RV…
On the Effect of Stellar Activity on Low-resolution Transit Spectroscopy and the Use of High Resolution as Mitigation
Frédéric Genest, David Lafrenière, Anne Boucher +4
We present models designed to quantify the effects of stellar activity on exoplanet transit spectroscopy and atmospheric characterization at low (R = 100) and high (R = 100,000) sp…
The Astropy Problem
Demitri Muna, Michael Alexander, Alice Allen +151
The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Pyth…
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…
HiFLEx -- a highly flexible package to reduce cross-dispersed echelle spectra
Ronny Errmann, Neil Cook, Guillem Anglada-Escudé +8
We describe a flexible data reduction package for high resolution cross-dispersed echelle data. This open-source package is developed in Python and includes optional GUIs for most…
