Table 1.
Parameters for determining the level of the influence to the gas slab by the stars via SBs.
Default value | Comment | |
---|---|---|
The velocity of SB with respect to gas | ||
v | 10 km s−1 | This and the next parameter are used in |
phase space density in Eq. (A.17) | ||
σ | 20 km s−1 | The velocity dispersion of the stars |
vcol | 10 km s−1 | Sets the SB collapse in Eqs. (2) and (3) |
sr | 1.19 | SB scaling defined in Eq. (4). With |
vcol, it fixes SB lifetime tb = 71.58 Myr | ||
ρ⋆ | 0.1 M⊙ pc−3 | Stellar density used in (A.17) |
ρgas | 0.015 M⊙ pc−3 | Density of the gas hosting SB |
fb | 25 kpc−2 Gyr−1 | The rate SBs form; see Sect. 3.2.3 |
