MBM 12 : A Younger Version of the TW Hydrae Association ?
We present optical and infrared photometry of stars near the MBM 12 dark cloud. The optical data indicate that there are about 40 candidate pre–main sequence stars in the same area currently occupied by eight bona–fide PMS stars. Analysis of 2MASS data suggests that 60% of PMS candidates had been detected. Some of these show evidence of optically thick disks. Our study of the 2MASS data also re...
متن کاملAmmonia observations of the nearby molecular cloud MBM 12
We present NH3(1,1) and (2,2) observations of MBM 12, the closest known molecular cloud (65 pc distance), aimed to find evidence for on-going star formation processes. No local temperature (with a Trot upper limit of 12 K) nor linewidth enhancement is found, which suggests that the area of the cloud we mapped (∼ 15 size) is not currently forming stars. Therefore, this close “starless” molecular...
متن کاملAdaptive optics imaging of the MBM 12 association Seven binaries and an edge - on disk in a quadruple system ⋆
We report adaptive optics (AO) observations of the young and nearby association MBM 12 obtained with the Canada-France-Hawaii Telescope. Our main observational result is the discovery of six new binary and the confirmation of HD 17332, already known as a binary. We also detected a possible quadruple system. It is composed of the close binary LkHα 263 AB (separation of ∼ 0.41 ′′), of LkHα 262 lo...
متن کاملPSPC observations of T Tauri stars in MBM 12 ?
We present the ROSAT PSPC pointed and ROSAT All-Sky Survey (RASS) observations and the results of our low and high spectral resolution optical follow-up observations of the T Tauri stars (TTS) and X-ray selected T Tauri star candidates in the region of the high galactic latitude dark cloud MBM12 (L1453-L1454, L1457, L1458). Previous observations have revealed 3 “classical” T Tauri stars and 1 “...
