Abstract

MARVEL is a novel facility targeting extreme-precision radial velocity observations. Dedicated to confirming and characterizing planet candidates from the TESS and future PLATO missions, MARVEL will provide mass measurements of a multitude of exoplanets. The MARVEL instrument consists of an array of four 80-cm robotic telescopes, linked to one state-of-the-art high-resolution echelle spectrograph, through a set of optical fibers. MARVEL can observe the radial velocities of four different stars simultaneously or, alternatively, combine the flux from four telescopes pointing to a single faint target in one spectrum. It will be installed next to the Mercator Telescope at the Roque De Los Muchachos Observatory on La Palma (SPAIN). MARVEL is designed and built by a KU Leuven (Belgium) led consortium, with contributions from Australia, Austria, Denmark, Germany, Spain, Sweden and the UK.
