Parameters described on this page: SF_CREATE_STAR_SCHEME, SF_CREATE_STAR_RSEED, SF_CREATE_STAR_DET_RANDOM, SF_CREATE_STAR_MIN_LEVEL, SF_CREATE_STAR_MIN_GAS_DENS, SF_CREATE_STAR_MASS_EFF, SF_CREATE_STAR_MIN_STAR_MASS, SF_CREATE_STAR_MAX_STAR_MFRAC,
Parameters below are shown in the format: Name (Valid Values) [Default Value]
-
- Description: Star formation schemes. See Sec.3.2 in Kim et al. 2016 and Sec.2.4 in Goldbaum et al. 2015 for the AGORA star formation scheme.
- Restriction: Only applicable when enabling the compilation option --star_formation.
-
- Description: Random seed used by star formation.
- Restriction: Only applicable when enabling the compilation option --star_formation.
-
SF_CREATE_STAR_DET_RANDOM(0=off, 1=on; <0 → set by --bitwise_reproducibility) [-1]- Description: Make random numbers deterministic (i.e., independent of OpenMP and MPI). Needed for the bitwise reproducibility.
- Restriction: Only applicable when enabling the compilation option --star_formation.
-
SF_CREATE_STAR_MIN_LEVEL(≥0; <0 → MAX_LEVEL) [0]- Description: Minimum AMR level allowed to form stars.
- Restriction: Only applicable when enabling the compilation option --star_formation.
-
SF_CREATE_STAR_MIN_GAS_DENS(≥0.0) [1.0e1]-
Description:
Minimum gas density allowed to form stars.
See the
$\rho_{\rm gas,\ thres}$ in Eq.(4) in Kim et al. 2016. Note that the input value should always be in units of HI count/cm^3, and it will be converted internally to the gas mass density as$m_H\times$ HI count/cm^3 (i.e., assuming the gas is composed of only HI and the mean molecular weight$\mu=1$ ). - Restriction: Only applicable when enabling the compilation option --star_formation.
-
Description:
Minimum gas density allowed to form stars.
See the
-
SF_CREATE_STAR_MASS_EFF(0.0 < input ≤ 1.0) [1.0e-2]-
Description:
Gas-to-star mass conversion efficiency.
See the
$\epsilon_*$ in Eq.(4) in Kim et al. 2016. - Restriction: Only applicable when enabling the compilation option --star_formation.
-
Description:
Gas-to-star mass conversion efficiency.
See the
-
SF_CREATE_STAR_MIN_STAR_MASS(≥0.0) [0.0]-
Description:
Minimum star particle mass for the stochastical star formation.
See the
$m_{\rm sf}$ in Eq.(5) in Goldbaum et al. 2015. Note that the input value should always be in units of Msun. - Restriction: Only applicable when enabling the compilation option --star_formation.
-
Description:
Minimum star particle mass for the stochastical star formation.
See the
-
- Description: Maximum gas mass fraction in a cell allowed to convert to the mass of the star per substep.
- Restriction: Only applicable when enabling the compilation option --star_formation.
