Parallax of the L4.5 dwarf 2M1821 $+$ 14 from high-precision astrometry with OSIRIS at GTC

J. Sahlmann, P. F. Lazorenko, H. Bouy +4

We used the OSIRIS camera at the 10.4 m Gran Telescopio Canarias (GTC) to monitor the astrometric motion of the L4.5 dwarf 2M1821 $+$ 14 over 17 months. The astrometric residuals of…

Classical T Tauri stars with VPHAS $+$ : I: H $α$ and $u$ -band accretion rates in the Lagoon Nebula M8

V. M. Kalari, J. S. Vink, J. E. Drew +8

We estimate the accretion rates of 235 Classical T Tauri star (CTTS) candidates in the Lagoon Nebula using $ug r i$ H $α$ photometry from the VPHAS+ survey. Our sample consists of star…

DE0823 $-$ 49 is a juvenile binary brown dwarf at 20.7 pc

J. Sahlmann, A. J. Burgasser, E. L. Martín +6

Astrometric monitoring of the nearby early-L dwarf DE0823 $-$ 49 has revealed a low-mass companion in a 248-day orbit that was announced in an earlier work. Here, we present new astr…
