BD-14 3065b (TOI-4987b) 2D spectra
Listed in IVOA Registry (Virtual Observatory)
The present study confirms BD-14 3065b as a transiting planet-brown dwarf in a triple-star system, with a mass near the deuterium-burning boundary.
Description
BD-14 3065b has the largest radius observed within the sample of giant planets and brown dwarfs around post-main sequence stars. Its orbital period is 4.3 days and it transits a subgiant F-type star with a mass of M*=1.41+/-0.05M_{sun}_, a radius of R*=2.35+/-0.08R_{sun}_, an effective temperature of Teff=6935+/-90K, and a metallicity of -0.34+/-0.05dex.
By combining TESS photometry with high-resolution spectra acquired with the TRES and Pucheros+ spectrographs, we measured a mass of Mp = 12.37+/-0.92M_Jup_ and a radius of Rp = 1.926+/-0.094R_Jup_. Our discussion of potential processes that could be responsible for the inflated radius led us to conclude that deuterium burning is a plausible explanation for the heating taking place in BD-14 3065b's interior. Detections of the secondary eclipse with TESS photometry enabled a precise determination of the eccentricity, ep=0.066+/-0.011, and reveal that BD-14 3065b has a brightness temperature of 3520+/-130K.
