DRAGraces: A pipeline for the GRACES high-resolution spectrograph at Gemini
André-Nicolas Chené, Shunyuan Mao, Michael Lundquist +2
This paper describes the software DRAGraces (Data Reduction and Analysis for GRACES), which is a pipeline reducing spectra from GRACES (Gemini Remote Access to the CFHT ESPaDOnS Sp…
New constraints on the planetary system around the young active star AU Mic. Two transiting warm Neptunes near mean-motion resonance
E. Martioli, G. Hébrard, A. C. M. Correia +2
AU Mic is a young, active star whose transiting planet was recently detected. We report our analysis of its TESS data, where we modeled the BY Draconis type quasi-periodic rotation…
Investigating the young AU~Mic system with SPIRou: large-scale stellar magnetic field and close-in planet mass
Baptiste Klein, Jean-François Donati, Claire Moutou +12
We present a velocimetric and spectropolarimetric analysis of 27 observations of the 22-Myr M1 star AU Microscopii (Au Mic) collected with the high-resolution (0.98-2.35 …
Determining the true mass of radial-velocity exoplanets with Gaia: 9 planet candidates in the brown-dwarf/stellar regime and 27 confirmed planets
Flavien Kiefer, Guillaume Hébrard, Alain Lecavelier +3
Mass is one of the most important parameters for determining the true nature of an astronomical object. Yet, many published exoplanets lack a measurement of their true mass, in par…
SPIRou: nIR velocimetry & spectropolarimetry at the CFHT
J. -F. Donati, D. Kouach, C. Moutou +63
This paper presents an overview of SPIRou, the new-generation near-infrared spectropolarimeter / precision velocimeter recently installed on the 3.6-m Canada-France-Hawaii Telescop…
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…
