SPIRou near-infrared spectropolarimetry of the ultra-hot Jupiter KELT-9b: tentative detection of the planet magnetic field

Alexis Lavail, Florian Debras, David Rogé Royo +23

Exoplanetary magnetic fields govern atmospheric escape and circulation but have eluded detection in close-in planets. In the ultra-hot Jupiter KELT-9b, atmospheric dynamo is predic…

Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS

Alexandrine L'Heureux, René Doyon, Charles Cadieux +57

The TRAPPIST-1 system is well-known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs…

A massive hot Jupiter orbiting a metal-rich early-M star discovered in the TESS full frame images

Tianjun Gan, Charles Cadieux, Farbod Jahandar +41

Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems remains u…

Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops

Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126

HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …

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…
