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
