Synthetic populations and trajectories for sdB stars ejected from the single degenerate helium donor channel for thermonuclear supernovae

This repository is a supplement to a journal paper (Neunteufel+ 2022) and contains the synthetic populations of sdB stars and sdB remnants ejected from the single degenerate helium donor channel for thermonuclear supernovae. See Neunteufel+ 2021 and Neunteufel+ 2022 for simulation parameters. 

Synthetic populations, including initial and final positions, are contained in the MXX-out.tr (XX=10..15) files where XX is the mass of the WD companion divided by 0.1 solar masses. Each population is a snapshot of stars ejected at the end of a 300 Myr period. (Note that stellar lifetimes are not taken into account here. See Neunteufel+ 2022 on how stellar lifetimes should be truncated in order to produce realistic populations.)

Columns:

Zeroth column (ID) is the ID of the trajectory. These are assigned consecutively.

First column (unnamed) indicates initial (0) and final (1) positions.

Third column (time) is the time since ejection in Myrs. Note that stars further down in the list were ejected earlier.

Fourth to Ninth columns (vx, y, vy etc..) are velocity (km/s) and position (kpc) in Gal. Carthesian coordinates (velocity first, position second)

Tenth to Twelfth column are accelerations in Gal. carthesian coordinates 

Thirteenth column (v_space) is the total galactocentric space velocity (km/s) 

Fourteenth column (Phi) is the local Gal. potential according to Model 1 presented by Irrgang+2013

Fifteenth column (E_kin/E_pot) is the local kinetic energy of the object divided by its potential energy with respect to the Gal. potential.

Sixteenth column (rho) is the local Gal. baryon density according to Model 1 presented by Irrgang+2013

Seventeenth column (label_c) is the mass of the ejected sdB star or sdB remnant in solar masses.
