CDROM/AJ/V106/P0773 Mass Luminosity Relation (Henry & McCarthy 1993) ================================================================================ The Mass-Luminosity Relation for Stars of Mass 1.0 to 0.08 Solar Masses Todd J. Henry & Donald W. McCarthy, Jr. <1993, AJ, 106, 773> =1993AJ....106..773H ================================================================================ Abstract: Mass-luminosity relations determined at infrared wavelengths are presented for stars with masses 1.0 to 0.08 solar masses. Using infrared speckle imaging techniques on a sample of nearby binaries, we have been able to concentrate on the lower main sequence (Mass <= 0.5 solar masses), for which an accurate mass-luminosity calibration has remained problematic. In addition, the mass-visual luminosity relation for stars with 2.0 >= Mass >= 0.08 solar masses is produced by implementing new photometric relations linking V to JHK wavelengths for the nearby stars, supplemented with eclipsing binary information. These relations predict that objects with masses ~0.08 solar masses have M(K) ~ 10 and M(V) ~ 18.

The final sample includes 37 objects, all of which are members of binaries with main-sequence components, except for GL 166C, in which case component B is a white dwarf not used in the MLR derivations. -------------------------------------------------------------------------------- Byte-by-byte Description of file: table1.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 6 A6 --- Gliese Gliese number, from Catalog of Nearby Stars 7 1X --- --- Blank 8 A1 --- Note *[by ] Note flag 9 1X --- --- Blank 10-21 A12 --- Other Other name 22 1X --- --- Blank 23-25 F3.0 h RAh Right ascension (1950.0) 26-28 F3.0 min RAm R.A. 29-31 F3.0 s RAs R.A. 32 1X --- --- Blank 33 A1 --- DE- Sign of declination 34-35 F2.0 deg DEd Declination (1950.0) 36-38 F3.0 arcmin DEm Dec. 39-41 F3.0 arcsec DEs Dec. 42-48 F7.4 arcsec plx Parallax 49-54 F6.4 arcsec e_plx Parallax standard error 55 A1 --- n_plx *[ac ] Note flag for plx 56-61 F6.2 yr P Orbital period 62-67 F6.3 yr e_P Orbital period error 68 A1 --- n_e_P [* ] if e_P was estimated by the authors 69-74 F6.3 arcsec a Orbital semimajor axis 75-80 F6.3 arcsec e_a Orbital semimajor axis error 81 A1 --- n_e_a [* ] if e_a was estimated by the authors 82-88 F7.3 --- B Fractional mass of the secondary 89-94 F6.3 --- e_B Fractional mass of the secondary error 95 A1 --- n_e_B [* ] if e_B was estimated by the authors 96 1X --- --- Blank 97-99 A3 --- q *Orbit quality 100-101 2X --- --- Blank 102-123 A22 --- Ref *References -------------------------------------------------------------------------------- Notes for file: table1.dat -------------------------------------------------------------------------------- Note: 'b' see Mariotti et al.

Nearly all of the observations reported in Table 2 were made on the Steward Observatory 2.3 m telescope on Kitt Peak, with a few observations from the KPNO 3.8 m also on Kitt Peak. The overall format has multiple entries for each star, one entry for each observed wavelength. There is a blank line between the entries for each star.
