cds-question@unistra.freclipsing-binary-starsstellar-masseseffective-temperaturestellar-radiiThe mass-luminosity (M-L), mass-radius (M-R), and mass-effective temperature (M-T_eff_) diagrams for a subset of galactic nearby main-sequence stars with masses and radii accurate to {<=}3% and luminosities accurate to {<=}30% (268 stars) has led to a putative discovery. Four distinct mass domains have been identified, which we have tentatively associated with low, intermediate, high, and very high mass main-sequence stars, but which nevertheless are clearly separated by three distinct break points at 1.05, 2.4, and 7M_{sun}_ within the studied mass range of 0.38-32M_{sun}_. Further, a revised mass-luminosity relation (MLR) is found based on linear fits for each of the mass domains identified. The revised, mass-domain based MLRs, which are classical (L{propto}M^{alpha}^), are shown to be preferable to a single linear, quadratic, or cubic equation representing an alternative MLR. Stellar radius evolution within the main sequence for stars with M>1M_{sun}_ is clearly evident on the M-R diagram, but it is not clear on the M-T_eff_ diagram based on published temperatures. Effective temperatures can be calculated directly using the well known Stephan-Boltzmann law by employing the accurately known values of M and R with the newly defined MLRs. With the calculated temperatures, stellar temperature evolution within the main sequence for stars with M>1M_{sun}_ is clearly visible on the M-T_eff_ diagram. Our study asserts that it is now possible to compute the effective temperature of a main-sequence star with an accuracy of ~6%, as long as its observed radius error is adequately small (<1%) and its observed mass error is reasonably small (<6%).2015AJ....149..131Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/149/131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/MNRAS/382/1073 : M/L relation of intermediate-mass stars (Malkov+, 2007)J/MNRAS/357/497 : Kinematics of W UMa-type binaries (Bilir+, 2005)J/AJ/106/773 : Mass-luminosity relation (Henry+, 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/149/131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/149/131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/149/131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/149/131https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/149/131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/149/131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/149/131/table2 (The basic stellar parameters and relative errors of the stars selected for the calibration sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/131/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/131/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/131/table2?GETtext/xml+votable180.050000true3.964833360.43156670.005555555555555556Cone search capability for table J/AJ/149/131/table7 (Comparing published and calculated (empirical) effective temperatures)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/131/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/131/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/131/table7?GETtext/xml+votable180.050000true3.28833335.59529440.0055555555555555566/14 377 474 528 1212 1293 1317 1344 1397 1753 2849 2948 3049 3238 3256 3383 3384 3449 3712 3830 4037 4078 4592 4708 4819 5217 6340 6429 6669 6783 7089 7273 7321 7454 7675 8081 8124 8687 8917 9044 9084 9578 9857 10169 10305 12372 12474 12581 12911 13228 13263 13281 13705 13819 13935 14130 14179 14263 14276 14290 14308 14331 14431 14442 14445 14459 14555 14575 14577 14599 14630 14644 14666 14734 14761 14825 14924 15135 15137 15195 15237 15415 15519 15669 15686 15713 15803 15806 16070 16096 16226 16274 16443 18309 18468 18673 18722 18895 19485 20271 20803 20853 20903 21394 21438 21526 21641 21732 21866 22044 22147 22249 22289 22318 22652 22875 22971 22980 22993 23226 23229 23236 23749 23994 24256 24305 24415 25098 25991 26125 26179 27029 27281 27405 28384 28687 28711 28892 29077 29836 30065 30158 30268 30343 30358 30424 30502 30627 31065 31169 31174 31227 31335 31572 31838 31863 31977 31984 32217 32382 32788 33027 33321 34914 35055 35447 35862 36057 36612 36936 37012 37333 37357 37592 37779 37827 37923 38562 39917 40071 40279 40545 40656 40826 40891 41370 41534 41715 41921 42071 42394 42501 42674 42791 42955 43152 43282 43463 44795 45549 45900 48013 48782https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/149/131?format=asciidefaultJ/AJ/149/131/table2The basic stellar parameters and relative errors of the stars selected for the calibration sampleSimbadNameSimbad column added by the CDSmeta.idcharSeq[1/296] Running sequence numbermeta.idintprimaryNameStar namemeta.id;meta.maincharm_NameBinary component (primary or secondary)meta.code.multipcharTSimbad column added by the CDSmeta.ref.urlcharRAJ2000Hour of Right Ascension (J2000)pos.eq.ra;meta.mainDEJ2000Degree of Declination (J2000)pos.eq.dec;meta.mainMass[0.1/31] Stellar Mass (1)solMassphys.massfloate_Mass[0.001/0.03] Relative uncertainty in Mass (1)stat.error;phys.massfloatRad[0.2/9.4] Stellar radius R/R_{Sun}_ (1)solRadphys.size.radiusfloate_Rad[0.002/0.03] Relative uncertainty in Rad (1)stat.error;phys.size.radiusfloatTeff[2952/43000] Published effective temperature (1)Kphys.temperature.effectiveinte_Teff?
