J. 113 1458 1997 1997AJ....113.1458H V/70 : CNS3 (Nearby Stars, Preliminary 3rd Version; Gliese+ 1991) Stars, nearby Stars, M-type Spectroscopy Space velocities Stars, distances The Third Catalogue of Nearby Stars (Gliese & Jahreiss, "Preliminary Version of the third Catalogue of Nearby Stars" (CNS3), 1991, catalog <V/70>) includes over 1850 stars which lie north of Dec.= -30{deg} and are either identified as spectral type M, or are unclassified but with an absolute visual magnitude estimate M_V_ > +8.0. Although there is no uniformity in selection criteria, and many of the stars lack basic data (radial velocities, spectral types, accurate photometry), the observational properties of these stars underlie most estimates of the fundamental characteristics of the Galactic Disk. We have obtained optical spectroscopy of 1746 of the 1876 stars -- the remaining 130 are binary companions of brighter stars and inaccessible to our observations. These spectra allow us, first, to exclude 61 stars as either degenerates or as misclassified earlier-type (B-K) stars lying beyond the 25 pc limit; to establish radial velocities accurate to +/-10km/s for all stars confirmed as late-type dwarfs; to determine spectral types and absolute magnitudes from the TiO bandstrength, allowing more accurate distance estimates for stars with inaccurate (or no) trigonometric parallax measurements; and to identify stars with H{alpha} emission (chromospherically active stars) and with strong CaH absorption (perhaps including some metal-poor disk subdwarfs). We have determined the nearby-star luminosity function from complete samples derived by applying both the distance limits defined by Wielen (1974, Highlights of Astron. 3, 395) and by using limits derived from our own analysis. Spectroscopic data for the southern stars (Dec.<-30{deg}) in the PMSU survey are also presented. The data were combined with the data from paper I to obtain a list of all the magnetically active dMe stars in the survey.

Note that the V magnitude listed by LH88 is 8.07, while the CNS3 magnitude is 11.4 (photometric estimate). The authors observed a star of the latter magnitude. There is a nearby 8th magnitude SAO star (SAO 7382) - listed as K5, luminosity class unknown but mu~0arcsec/yr which Leggett & Hawkins may have observed by mistake. k: Spectral type from Kirkpatrick et al.

Gliese (1969, Veroff. Astr. Rechen-Instituts, Heidelberg, Nr. 22) lists a 'red companion at 8 arcseconds', but no companion brighter than R~17 was visible with the LCO Du Pont telescope. Bessell (1990A&AS...83..357B) lists colours of (B-V)=0.615, (V-I)=0.70, suggesting either a white dwarf companion or observations of a background star. b: Our spectrum indicates that this star is an M-dwarf, but the 6th magnitude primary, CP-73 2192, at 8 arcseconds distance prevents accurate bandstrength measurements. --- Bin Primary or secondary binary component --- RAh Right ascension, 2000 h RAm Right ascension, 2000 min RAs Right ascension, 2000 s DE- Declination sign --- DEd Declination, 2000 deg DEm Declination, 2000 arcmin DEs Declination, 2000 arcsec Src Source of position, as in main.dat --- VMag Absolute V magnitude mag r Distance pc e_r Distance uncertainty % Sample n=North (paper I), s=South (paper II) --- CNS3 Star number (row number in CNS3) --- m_CNS3 Multiplicity index on star --- TiO1 TiO1 index: F(6718-6723)/F(6703-6708) --- TiO2 TiO2 index: F(7058-7061)/F(7043-7046) --- TiO3 TiO3 index: F(7092-7097)/F(7079-7084) --- TiO4 TiO4 index: F(7130-7135)/F(7115-7120) --- TiO5 TiO5 index: F(7126-7135)/F(7042-7046) --- CaH1 CaH1 index: F(6380-6390)/F (6345-6355,6410-6420)) --- CaH2 CaH2 index: F(6814-6846)/F(7042-7046) --- CaH3 CaH3 index: F(6960-6990)/F(7042-7046) --- CaOH CaOH index: F(6230-6240)/F(6345-6354) --- Halpha H-alpha index: F(6560-6566)/F(6545-6555) --- Sample n=North (paper I), s=South (paper II) --- CNS3 Star number (row number in CNS3) --- m_CNS3 Multiplicity index on star --- pmRA Proper motion in right ascension, from CNS3 arcsec/yr pmDE Proper motion in declination, from CNS3 arcsec/yr RV Radial velocity km/s Note If no proper motions are available --- U U space velocity km/s V V space velocity km/s W W space velocity km/s VMag Absolute V magnitude (from main.dat) mag CNS3 Star number (row number in CNS3) --- Halp H-alpha index: F(6560-6566)/F(6545-6555) --- TiO2 TiO2 index: F(7058-7061)/F(7043-7046) --- TiO4 TiO4 index: F(7130-7135)/F(7115-7120) --- TiO5 TiO5 index: F(7126-7135)/F(7042-7046) --- Sp Spectral type --- Mv Absolute V magnitude mag Vmag V magnitude mag R-I R-I colour index mag V-I V-I colour index mag r_VRI Reference for VRI photometry --- V-K V-K colour index mag S(Hb) H{beta} flux 10-13mW/m2 S(Ha)/S(Hb) H{alpha} versus H{beta} flux ratio --- log(L(Ha)/Lbol) H{alpha} vs. bolometric luminosity ratio --- Mbol Bolometric magnitude mag CNS3 Star number (row number in CNS3) --- Halp H-alpha index: F(6560-6566)/F(6545-6555) --- TiO2 TiO2 index: F(7058-7061)/F(7043-7046) --- TiO4 TiO4 index: F(7130-7135)/F(7115-7120) --- TiO5 TiO5 index: F(7126-7135)/F(7042-7046) --- Sp Spectral type --- Mv Absolute V magnitude mag Vmag V magnitude mag V-I V-I colour index mag log(L(Ha)/Lbol) H{alpha} versus bolometric luminosity ratio --- log(LX/Lbol) X-ray versus bolometric luminosity ratio --- Mbol Bolometric magnitude mag paper1.texTables from paper I, latex paper2.texTables from paper II, latex Francois Ochsenbein CDS 1997May14It is a pleasure to thank Suzanne Hawley <slh@pillan.pa.msu.edu>, who kindly provided a latex version of the tables.
