Abstract:
This paper introduces a series of papers aiming to study the dozens of
low mass eclipsing binaries (EBLM), with F, G, K primaries, that have
been discovered in the course of the WASP survey. Our objects are
mostly single-line binaries whose eclipses have been detected by WASP
and were initially followed up as potential planetary transit
candidates. These have bright primaries, which facilitates
spectroscopic observations during transit and allows the study of the
spin-orbit distribution of F, G, K+M eclipsing binaries through the
Rossiter-McLaughlin effect.
Description:
For WASP-30: the data is composed of two TRAPPIST photometric
timeseries, one set of CORALIE radial velocities and one set of HARPS
radial velocities (remaining photometry in Anderson et al. 2011, Cat.
J/ApJ/726/L19).
For J1219-39, the data consist of one set of CORALIE radial velocities
and four photometric timeseries originating from the WASP-South
instrument.
They give evidence of an eclipsing brown dwarf orbiting WASP-30, and
of a low mass star eclipsing J1219-39.
