SSSPM J0829−1309: A new nearby L dwarf detected in SuperCOSMOS Sky Surveys

The SuperCOSMOS Sky Surveys provide a complete coverage of the Southern sky in three passbands (photographic BJ , R and I) and at different epochs (Hambly et al. 2001a,b,c). These data are the basis for a new high proper motion survey which aims at finding extremely red nearby dwarf stars and brown dwarfs. One of the first candidates, which is relatively bright (I = 16) but very red (R− I = 2.8...

The nearest cool white dwarf ( d ∼ 4 pc ) , the coolest M - type subdwarf ( sdM 9 . 5 ) , and other high proper motion discoveries ⋆

The nearest cool white dwarf (d ∼ 4 pc), the coolest M-type subdwarf (sdM9.5), and other high proper motion discoveries Abstract. We report the discovery of seven high proper motion stars with proper motions between about 0.7 and 2.2 arcsec/yr, all at relatively low Galactic latitudes (13 • < |b| < 35 •) and located in the southern sky. They were detected in a high proper motion search using mu...

A New Ultracool White Dwarf Discovered in the SuperCOSMOS Sky Survey

We present BJ , R59F and IN photometry, and optical and near-infrared spectroscopy, of a new ultracool white dwarf (UCWD) discovered in the SuperCOSMOS Sky Survey. The spectrum of SSSJ1556-0806 shows strong flux suppression due to the presence of collisionally induced absorption by molecular hydrogen (H2CIA), a feature characteristic of the cool, high density environments found in the atmospher...

APMPM 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...

The SuperCOSMOS Sky Survey . Paper III :

In this, the third in a series of three papers concerning the SuperCOSMOS Sky Survey, we describe the astrometric properties of the database. We describe the algorithms employed in the derivation of the astrometric parameters of the data, and demonstrate their accuracies by comparison with external datasets using the first release of data, the South Galactic Cap survey. We show that the celesti...
