New high-proper motion survey in the Southern sky
We present the discovery of about 100 new highproper motion stars in the region between 0 and 7 in right ascension and −63◦ and −32◦ in declination, with proper motions between 0.3 and 1.0 arcsec/yr. In addition we have obtained improved coordinates and photographic photometry for another about 100 already known high-proper motion stars in the same region. In this study we have made use of APM ...
متن کاملAPMPM J0237-5928: a new nearby active M5 dwarf detected in a high proper motion survey of the Southern sky
A new bright (R = 13.4) high proper motion star has been detected within our survey of the Southern sky using APM measurements of UK Schmidt plates (Scholz et al. 1999). This star, APMPM J0237-5928 showing the largest proper motion (μ = 0.77 arcsec/yr) among the newly discovered relatively bright (11 < R < 15) proper motion stars in 40 UKST fields, was identified with an X-ray source in the ROS...
متن کاملHigh Proper Motion Objects from the UKIDSS Galactic Plane Survey
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a 7 year effort to survey ∼1800 deg of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K band data, with a baseline of 2 to 8 years, for the purpose of investigating variability and measuring proper motions. We have calculated proper motions for 167 Million sources in a 900 deg area located a...
متن کاملSpectroscopy of New High Proper Motion Stars in the Northern Sky . I .
We define an enhanced spectral classification scheme for M dwarf stars, and use it to derive spectral classification of 104 northern stars with proper motions larger than 0.5 yr which we discovered in a survey of high proper motion stars at low galactic latitudes. The final tally is as follows: 54 M dwarfs, 25 sdK and sdM subdwarfs, 14 esdK and esdM extreme subdwarfs, and 11 DA and DC white dwa...
متن کاملExtremely faint high proper motion objects from SDSS stripe 82 ⋆ Optical classification spectroscopy of about 40 new objects
Aims. By pushing the magnitude limit of high proper motion surveys beyond the limit of photographic Schmidt plates we aim at the discovery of nearby and very fast low-luminosity objects of different classes: cool white dwarfs (CWDs), cool subdwarfs (sd), and very low-mass stars and brown dwarfs at the very faint end of the main sequence (MS). Methods. The deep multi-epoch Sloan Digital Sky Surv...
