The gravitational mass of Proxima Centauri measured with SPHERE from a microlensing event

Zurlo, A. Gratton, R. Mesa, D.

Proxima Centauri, our closest stellar neighbour, is a low-mass M5 dwarf orbiting in a triple system. An Earth-mass planet with an 11 day period has been discovered around this star. The star's mass has been estimated only indirectly using a mass-luminosity relation, meaning that large uncertainties affect our knowledge of its properties. To...

New spectro-photometric characterization of the substellar object HR 2562 B using SPHERE

Mesa, D. Baudino, J.-L. Charnay, B.

Aims: HR 2562 is an F5V star located at 33 pc from the Sun hosting a substellar companion that was discovered using the Gemini planet imager (GPI) instrument. The main objective of the present paper is to provide an extensive characterization of the substellar companion, by deriving its fundamental properties. Methods: We observed HR 2562 with...
