Abstract:
In this paper, we present new specific stellar models for the Large
Magellanic Cloud. In order to take the observational uncertainties in
the chemical composition into account, we have computed two grids:
(X, Z) = (0.730, 0.010) and (0.739, 0.007). The covered mass range was
0.80 up to 125M_☉. The effects of rotation can be investigated by
using the gravity-darkening exponents that are available for each
track. The tidal constant E2, depth of the convective outer zone,
and the radius of gyration are computed and presented in a suitable
format for studying the tidal evolution of a given close binary. The
isochrones (and also those corresponding to the previous grids) will
be presented in a future paper.

Global notes:
Note (G1): Overshooting value is
0 = without overshooting,
1 = with overshooting.
For all models, alpha = 1.680 .
For models with overshooting, alphaOV= 0.200.
