A sub-Neptune planet around TOI-1695 discovered and characterized with SPIRou and TESS

F. Kiefer, G. Hébrard, E. Martioli +39

TOI-1695 is a V-mag=13 M-dwarf star from the northern hemisphere at 45pc from the Sun, around which a 3.134-day periodic transit signal from a super-Earth candidate was identif…

APERO: A PipelinE to Reduce Observations -- Demonstration with SPIRou

Neil James Cook, Étienne Artigau, René Doyon +14

With the maturation of near-infrared high-resolution spectroscopy, especially when used for precision radial velocity, data reduction has faced unprecedented challenges in terms of…

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…

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…

Line-by-line velocity measurements, an outlier-resistant method for precision velocimetry

Étienne Artigau, Charles Cadieux, Neil J. Cook +14

We present a new algorithm for precision radial velocity (pRV) measurements, a line-by-line (LBL) approach designed to handle outlying spectral information in a simple but efficien…

TESS discovery of a sub-Neptune orbiting a mid-M dwarf TOI-2136

Tianjun Gan, Abderahmane Soubkiou, Sharon X. Wang +60

We present the discovery of TOI-2136b, a sub-Neptune planet transiting every 7.85 days a nearby M4.5V-type star, identified through photometric measurements from the TESS mission.…

Validation of 13 Hot and Potentially Terrestrial TESS Planets

Steven Giacalone, Courtney D. Dressing, Christina Hedges +108

The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially…

TOI-1759 b: a transiting sub-Neptune around a low mass star characterized with SPIRou and TESS

Eder Martioli, Guillaume Hébrard, Pascal Fouqué +57

We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from SPIRo…

A Possible Alignment Between the Orbits of Planetary Systems and their Visual Binary Companions

Sam Christian, Andrew Vanderburg, Juliette Becker +111

Astronomers do not have a complete picture of the effects of wide-binary companions (semimajor axes greater than 100 AU) on the formation and evolution of exoplanets. We investigat…

TOI-1442 b and TOI-2445 b: two potentially rocky ultra-short period planets around M dwarfs

G. Morello, H. Parviainen, F. Murgas +52

Context. Exoplanets with orbital periods of less than one day are known as ultra-short period (USP) planets. They are relatively rare products of planetary formation and evolution…
