The properties of main-sequence stars from Hipparcos data

ESA SP PUBL 402 (1997) 279-282

N Houk, CM Swift, CA Murray, MJ Penston, JJ Binney

We received a sample of 6840 Hipparcos stars south of declination -26 degrees that (i) have MK spectral types in the Michigan catalogues and (ii) had spectroscopic parallaxes that placed them within 80 pc of the Sun. Of these, 3727 are well determined as luminosity class V and actually lie within 100 pc. From this subsample we can determine the distribution in M-V of main-sequence stars of given spectral type for spectral types that range from early F to early K. These distributions are significantly non-Gaussian, but when fitted to Gaussians they yield central values of M-V in good agreement with earlier estimates of the absolute magnitudes of main-sequence stars. We also determine anew the distribution of B-V at each spectral type. We find that the dispersion in B-V at given spectral type is very small.


The luminosity function of main-sequence stars within 80 parsecs from Hipparcos data

ESA SP PUBL 402 (1997) 485-488

CA Murray, MJ Penston, JJ Binney, N Houk

The basic data discussed here consist of parallaxes and apparent magnitudes of more than 6000 stars with delta < -26 degrees from the Hipparcos Catalogue which were selected from the Michigan Spectral Catalogue to have estimated spectroscopic distances within 80 parsecs. The statistical properties of the sample are briefly discussed, and the luminosity function of main sequence stars is determined by the maximum-volume method from nearly 3000 stars with observed parallaxes greater than 12.5 mas.


The kinematics of main-sequence stars from Hipparcos data

ESA SP PUBL 402 (1997) 473-477

JJ Binney, W Dehnen, N Houk, CA Murray, MJ Penston

We analyze a kinematically unbiased sample of 5610 stars around the south celestial pole that (i) have MK spectral types in the Michigan catalogues with luminosity class V and (ii) had photometric parallaxes that placed them within 80 pc of the Sun. We bin the stars by B - V and determine for each bin the solar motion from proper motions alone. As expected, the U and W components of the derived solar motions do not vary significantly from bin to bin, while the V component varies systematically. As the classic Stromberg relation predicts, V is a linear function of the variance S-2 within each bin around the solar motion. Extrapolating V (S-2) to S = 0 we determine the solar motion with respect to the LSR, obtaining a significantly smaller value of V than is usually employed. Parenago's discontinuity in the dependence of S-2 on spectral type emerges with exceptional clarity.
