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.
