[BUG]: overflow warning `step_CEE`

[maxbriel]

Describe the bug
An overflow warning is given in step_CEE

../POSYDON/posydon/binary_evol/CE/step_CEE.py:1506: RuntimeWarning: overflow encountered in power

Expected behavior
No such warning should be happening.

POSYDON Version:
v2.2 PR

thanks @maxbriel , do you see this issue all the time or do you have an example binary to test against? It seems like it's coming from this line:

rc2_i = 10**comp_star.interp1d['log_R'](t_i)

Just to jump in, I see this issue very frequently as well (using the current state of v2.2). Not sure if it's always associated with the rc2_i variable, as I get the overflow warning more often than the type error, but here's an example of a failed binary:

File ".../POSYDON-public/posydon/binary_evol/CE/step_CEE.py", line 1504, in adjust_secondary_radius
    rc2_i = 10**comp_star.interp1d['log_R'](t_i)
