APMPM J0237-5928: a new nearby active M5 dwarf detected in a high proper motion survey of the Southern sky.

SCHOLZ R.-D., IRWIN M., SCHWEITZER A. and IBATA R.

Abstract (from CDS):

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, A&A, submitted) This star, APMPM J0237-5928 showing the largest proper motion (µ=0.77arcsec/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 ROSAT All Sky Survey, 1RXS J023630.5-592827. The optical spectrum is typical of an M5 dwarf and shows strong emission lines. An effective temperature Teff=3100K and solar metallicity were determined using ``NextGen'' model atmospheres for M dwarfs (Hauschildt, Allard & Baron, 1999) A distance between 11 and 14.5pc is estimated based on the spectral type and on the comparison of the observed spectrum with the models. With this distance we determine the relatively high X-ray luminosity logLX=27.8 for a late-type M dwarf. The heliocentric space motion was obtained as (U,V,W)=(-39,-28,-27)±(8,5,6)km/s.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
