TYCHO-6.9: other stars

TYCHO 6.9: Other stars

Many initial models for different sequences are provided in the directory initial.dir.

p700000     0.7 solar masses  Asplund solar composition
m100000     1.0 solar masses  Asplund solar composition
m200000     2.0 solar masses  Asplund solar composition
m400000     4.0 solar masses  Asplund solar composition
m600000     6.0 solar masses  Asplund solar composition
m800000     8.0 solar masses  Asplund solar composition
b400000    16.0 solar masses  Asplund solar composition
b500000    32.0 solar masses  Asplund solar composition

These may be manipulated with the program genex to scale the mass and radius, or change the compositions.

Testing your results.

In the directory tycho-6.9 there are several sequences which have already been run, besides the m6 sequence we have just done.

p7     0.7 solar masses   443 steps Asplund solar composition
m1     1.0 solar masses   516 steps Asplund solar composition
m2     2.0 solar masses  1218 steps Asplund solar composition
x2     2.0 solar masses  1499 steps Asplund solar composition/10

For example, to test the 0.7 solar mass evolution as computed on your machine, change the sequence identifier in params.d to

' Sequence identifier(keep this spacing).....' 'prefix'  'P7'

using a CAPITAL P to distinguish from the files already there, and

cp p700000 imodel
tycho6

to start the run from the p700000 initial model. You could reset ll in params.d to 443 to cover the same number of time steps.

' Number of timesteps for this run...........' 'll'        443
