  • We present a new radial velocity measurement that, together with a trigonometric parallax, proper motion and signs of low gravity from the literature, confirms that SDSS J111010.01+011613.1 is a new T5.5 bona fide member of AB Doradus. Fitting ≈ 6000 Folded-port InfraRed Echellette spectroscopy in the 1.20–1.33 μm region to BT-Settl atmosphere models yielded a radial velocity of 7.5 ± 3.8 km s−1. At such a young age (110–130 Myr), current evolution models predict a mass of ∼10–12 , thus placing… CONTINUE READING
