ADC_Keywords: Isochrones
Description:
The following data and program files are provided:
1. Evolutionary tracks/isochrones from VandenBerg (1985, ApJS, 58, 711):
"Evolution of 0.7-3.0 Solar masses stars having -1.0<=[Fe/H]<=0.0"
V852M3.TRK and V852M3.ISO - Y=0.25, Z=0.0017
V853M3.TRK and V853M3.ISO - Y=0.25, Z=0.0030
V856M3.TRK and V856M3.ISO - Y=0.25, Z=0.0060
V851M2.TRK and V851M2.ISO - Y=0.25, Z=0.0100
V852M2.TRK and V852M2.ISO - Y=0.25, Z=0.0169
Note that 'V852M3' represents 'V(andenBerg 19)85' results for a metal
abundance '2 (times 10 to the) M(inus) 3'. That is, the file name
gives the initials of the author(s), the year of publication, and the
assumed value of Z (the mass-fraction metal abundance) to one
significant figure. This convention is used for all data files in
this package. Reference should be made to V85 to assist the
identification of the quantities that are contained in the files.
Note that, in the case of the above .ISO files, a zero-age main
sequence is given as well as isochrones for ages from 0.3 to 15 Gyr.
2. Isochrones from VandenBerg & Bell (1985, ApJS, 58, 561) and Bell &
"Theoretical isochrones for Globular Clusters"
VandenBerg (1987, ApJS, 63, 335):
VB851M4A.ISO and VB851M4B.ISO - Z=0.0001 (Y=0.2 & Y=0.3)
VB853M4A.ISO and VB853M4B.ISO - Z=0.0003 (Y=0.2 & Y=0.3)
VB851M3A.ISO and VB851M3B.ISO - Z=0.0010 (Y=0.2 & Y=0.3)
VB853M3A.ISO and VB853M3B.ISO - Z=0.0030 (Y=0.2 & Y=0.3)
VB856M3A.ISO and VB856M3B.ISO - Z=0.0060 (Y=0.2 & Y=0.3)
Note that 'A' or 'B' has been appended to the file name to indicate
Y=0.2 or Y=0.3, respectively. (The file name has been limited to 8
characters so as not to exceed the maximum length permitted on IBM
machines.) Once again, reference should be made to the two published
papers to identify the quantities that have been saved.
3. Evolutionary tracks/isochrones from VandenBerg & Laskarides (1987,
ApJS, 64, 103):
"Theoretical isochrones for old, super-metal-rich stars"
VL873M2A.TRK and VL873M2A.ISO - Y=0.25, Z=0.03
VL873M2B.TRK and VL873M2B.ISO - Y=0.35, Z=0.03
VL876M2A.TRK and VL876M2A.ISO - Y=0.25, Z=0.06
VL876M2B.TRK and VL876M2B.ISO - Y=0.35, Z=0.06
VL871M1A.TRK and VL871M1A.ISO - Y=0.25, Z=0.10
VL871M1B.TRK and VL871M1B.ISO - Y=0.35, Z=0.10
Note that 'A' or 'B' has been appended to the file name to indicate
Y=0.25 or Y=0.35, respectively. The .TRK files are self-explanatory;
in the case of the .ISO files, each line gives 'mass, Mbol, and log
Teff' values for each of three consecutive points along an isochrone.
No attempt has been made to transform the models to the observed plane
4. Isochrones from Proffitt & VandenBerg (1991, ApJS 77, 473):
"Implication of He diffusion for globular cluster isochrones and
luminosity functions":
PV911M4S.ISO and PV911M4D.ISO - Z=0.0001 (without/with diffusion)
PV911M3S.ISO and PV911M3D.ISO - Z=0.0010 (without/with diffusion)
PV914M3S.ISO and PV914M3D.ISO - Z=0.0040 (without/with diffusion)
Note that 'S' and 'D' have been appended to the file name to indicate
'standard' or 'diffusive' calculation, respectively. The Z values
given above refer to the mass-fraction of metals exclusive of the
assumed oxygen abundance enhancement. (See point 6. below)
5. Isochrones from Bergbusch & VandenBerg (1992, ApJS 81, 163)
"Oxygen-enhanced models for globular cluster stars. II.
Isochrones and luminosity functions"
BV921M4.ISO - Z=0.0001
BV922M4.ISO - Z=0.00017
BV923M4.ISO - Z=0.0003
BV924M4.ISO - Z=0.0004
BV926M4.ISO - Z=0.0006
BV921M3.ISO - Z=0.0010
BV922M3.ISO - Z=0.0017
BV923M3.ISO - Z=0.0030
BV924M3.ISO - Z=0.0040
BV926M3.ISO - Z=0.0060
Note that the Z values given above refer to the mass-fraction of
metals exclusive of the assumed oxygen abundance enhancement.
6. The luminosity function code (LUMVAX.FOR or LUMIBM.FOR):
The names specify either a VAX or an IBM version of the code which
can process any of the files in 4. or 5. above to produce tables of
isochrones and luminosity functions. The tables which are generated
should be identical to the tables that appear in the Proffitt &
VandenBerg and the Bergbusch & VandenBerg studies. The first several
lines in the two codes describe what is required to execute them.
*** The tables can be generated as a set of files *.lf either
on VAX (@make) or on Unix platforms (make)
7. COLLO.TXT and COLHI.TXT are the color transformation and bolometric
correction data used to transpose the models from the theoretical to
the observed plane. The user may wish to extract SUBROUTINE COLOR
from LUMVAX.FOR or LUMIBM.FOR to derive colors for any [Fe/H]
(preferably between 0.0 and -2.0), log g, and log Teff. Reference
should be made to VandenBerg (1992, ApJ 391, 685) for a discussion
of the transformation relations.
Should the user encounter any difficulty with this package, he/she is
invited to contact Don VandenBerg (davb@uvvm.uvic.ca).
