Chemical Composition (Asplund, M., Grevesse, N., Sauval, A.J., Scott, P., 2009, ARA&A47, 481A)
X
–
hydrogen abundance
Z
–
heavy element abundance
AC
–
MLT parameter (mixing-length theory); AC = alpha convective = lconv/Hp, where lconv - mixing length, Hp - local pressure scale height
AO
–
convective overshooting parameter; AO = alpha overshooting = dover/Hp, where dover - convective overshooting
V
–
initial equatorial rotational velocity [km/s]
Stellar oscillations were calculated from ZAMS to TAMS. The oscillation
files are called nad***.mrt, and are packed for each mass. The structure of
these files is as follows:
first line:
M=... Teff=... logL=... R=... logg=... Vrot=...
where
M
–
the stellar mass in solar units
Teff
–
logTeff
logL
–
logL/L๏
R
–
the stellar radius in solar units
logg
–
logg
second line:
l
n
sig
P[hrs]
fa[c/d]
fn[c/d]
COMPLEX F
ekg/ek
eta
where
l
–
the spherical harmonic degree, l
n
–
the radial order, n
sig
–
the dimensionless frequency defined as
P[hrs]
–
oscillation period in [h]
fa[c/d]
–
adiabatic oscillation frequency in [c/d]
fn[c/d]
–
adiabatic oscillation frequency in [c/d]
COMPLEX F
–
(two values) the ratio of the radiative flux perturbation to the radial displacement at the level of the photosphere
ekg/ek
–
ratio of the gravitational energy to the total kinetic energy; 0 for "pure" pressure modes, 1 for "pure" gravity modes
eta
–
instability parameter defined as η =
where W is the work integral. For unstable modes we have η > 0. The values of the η parameter
change from -1 (damping everywhere) to +1 (driving everywhere)
