This test case has 1 parts. Click to see a larger version of a plot. * Part 1 (``inlist_wd_stable_h_burn``) loads ``1.1M_lgTc_7.7.mod``, a prebuilt 1.1 |Msun| carbon oxygen white dwarf from the :ref:`make_co_wd` test suite in r13738 with an ``initial_mass`` of 6.4 |Msun|. The mass is relaxed to 1.0 |Msun|, the optical depth is relaxed to 300, and a hydrogen-rich composition is accreted at 2.5e7 |Msun|/yr. After about 100 year of evolution there is a hydrogen burning outburst followed by a period of stable hydrogen burning: .. image:: ../../../star/test_suite/wd_stable_h_burn/docs/grid_000829.svg :width: 100% pgstar commands used for the plots above: .. code-block:: console &pgstar file_white_on_black_flag = .true. ! white_on_black flags -- true means white foreground color on black background !file_device = 'png' ! png file_device = 'vcps' ! postscript pgstar_interval = 1 pgstar_left_yaxis_label_disp = 4.0 History_Track1_win_flag = .false.
