mcfacts.physics.tde

Module for TDE specific calculations.

mcfacts.physics.tde.check_tde_or_flip(star_retro_id_num, star_retro_mass, star_retro_log_radius, star_retro_orb_ecc, star_retro_orb_a, smbh_mass, r_g_in_meters)

Retrograde stars that flip to prograde are TDEs if they are inside the disk’s tidal disruption radius and have sufficiently high eccentricity.

Parameters:

  • star_retro_id_num (numpy.ndarray) – ID numbers of retrograde stars that may flip to prograde

  • star_retro_mass (numpy.ndarray) – Star mass [Msun] with float type

  • star_retro_log_radius (numpy.ndarray) – Star log radius/Rsun with float type

  • star_retro_orb_ecc (numpy.ndarray) – Star orbital eccentricity

  • star_retro_orb_a (numpy.ndarray) – Star semi-major axis wrt SMBH with float type

  • smbh_mass (float) – Mass [Msun] of the SMBH

  • r_g_in_meters (float) – Gravitational radius of the SMBH in meters

Returns:

  • tde_id_num (numpy.ndarray) – ID numbers of stars that will become TDEs

  • flip_id_num (numpy.ndarray) – ID numbers of stars that will flip to prograde
