We report the discovery of TOI-530b, a transiting giant planet around an M0.5V dwarf, delivered by the Transiting Exoplanet Survey Satellite (TESS). The host star is located at a distance of 147.7 ± 0.6 pc with a radius of R∗ = 0.54 ± 0.03 R and a mass of M∗ = 0.53 ± 0.02 M . We verify the planetary nature of the transit signals by combining ground-based multi-wavelength photometry, high resolution spectroscopy from SPIRou as well as high-angular-resolution imaging. With V = 15.4 mag, TOI530b… 


SPIRou: A NIR Spectropolarimeter/High-Precision Velocimeter for the CFHT
SPIRou is a near-infrared (nIR) spectropolarimeter / velocimeter for the Canada-France-Hawaii Telescope (CFHT), that will focus on two forefront science topics, (i) the quest for habitable Earth-like
Doppler Tomography
I review the method of Doppler tomography which is widely used to understand the complex emission line profile variations displayed by accreting binary stars. Doppler tomography uses the information
