Global analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey. (2020)

Keywords : atmospheric effects - techniques photometric - planets and satellites: detection

Abstract:We conducted a global analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey - a prototype of the SPECULOOS transit search conducted with the TRAPPIST-South robotic telescope in Chile from 2011 to 2017 - to estimate the occurrence rate of close-in planets such as TRAPPIST-1b orbiting ultra-cool dwarfs. For this purpose, the photometric data of 40 nearby ultra-cool dwarfs were reanalysed in a self-consistent and fully automated manner starting from the raw images. The pipeline developed specifically for this task generates differential light curves, removes non-planetary photometric features and stellar variability, and searches for transits. It identifies the transits of TRAPPIST-1b and TRAPPIST-1c without any human ...(more)

We tabulate the light curves (I + z filter) of 40 nearby ultra-cool dwarfs. The data were collected by the TRAPPIST-South telescope in Chile from 2011 to 2017 and used to compute the estimated planet yield depending on the occurrence rate of planets around ultra-cool dwarfs.
