cds-question@unistra.frstellar-evolutionary-modelsTables are given for all of the evolutionary tracks in the paper, which represent the evolution from the Zero-Age Horizontal Branch to a point either late in the AGB evolution, or in many cases to a point on the white dwarf cooling sequences. There are sequences for 8 different compositions. The original grid of tracks comprises several tens of thousands of models. In order to make this grid easy to use while not seriously compromising the representation of the evolution, much shorter tables have been derived for the general user. The data given here have been derived from these original calculations by linear and quadratic interpolation routines. For the HB phase, the evolution is represented at a fixed set of core helium values. After core exhaustion, the table points are at fixed intervals along the evolutionary path. The compositions in the tables are denoted as follows: -------------------------------------------------- Filename YHB [Fe/H] [O/Fe] Mc -------------------------------------------------- g14.dat 0.245 -2.26 0.50 0.495 e64.dat 0.247 -1.48 0.60 0.485 j63.dat 0.257 -0.47 0.23 0.475 z22.dat 0.288 +0.00 0.00 0.469 z42.dat 0.292 +0.39 0.00 0.464 z62.dat 0.289 +0.58 0.00 0.458 yz42.dat 0.356 +0.43 0.00 0.454 yz62.dat 0.459 +0.71 0.00 0.434 ------------------------------------------------- The columns give respectively: 1 Age in Myr since ZAHB 2 Central helium fraction 3 log Te (effective temperature, Kelvin) 4 log L (surface luminosity) in solar units 5 log g (surface gravity, cgs units) 6 log R (radius, cm) 7 Mass at peak energy production rate of hydrogen burning shell (solar units) 8 log Tc (central Temperature, Kelvin) 9 log rho_c (central density cgs units) The fortran format for the data tables is: '(f10.5,8(2x,f7.4))' for the first header line the format is: '("Track: ",i4,"lines Mass = ",f5.3," [Fe/H] = ",f5.2," [O/Fe] = ", f5.2," Y = ", f5.3)' while the second header line containing the column titles can of course be read as a character string ( format = '(a)' ). More specialized data is available in some cases from the first author, who should be contacted if other data are needed (see AAS directory for current address.)1993ApJ...419..596Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VI/65CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/54 : Horizontal Branch Stellar Model Calculations (Dorman 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/65https://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/65https://vizier.iucaa.in/viz-bin/votable?-source=VI/65http://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultVI/65/modelsTable with all modelsrecnoRecord number assigned by the VizieR team.
