Version 1.4.1

1.4.1 (2012-04-11)

• Added SN yields dataset from Leung & Nomoto 2020
• Added SN yields datasets from three different models in Leung & Nomoto 2018

Version 1.4.0

1.4.0 (2021-03-18)

• New supernovae module to add SN yields datasets
• Added sn_yields setting
• Added SN yields dataset from Seitenzahl et al. 2013

Version 1.3.0

1.3.0 (2020-12-10)

• SuperNova rates are now computed accounting for the total number of stars created per unit of stellar mass
• Added new DTD option: Greggio, L. 2005
• Added dataset of solar abundances from Lodders et al. 2019
• Added two_steps_t option for integration_step setting: The integration will use two time steps: [half the lifetime of a 100 solar masses star for the given metallicity] as time step for stars bigger than 4 solar masses, and 100 times that for less massive stars. If this option is selected the total_time_steps setting is ignored
• Added fixed_n_steps option for integration_step setting: The integration will take exactly the number of time steps specified in the next two settings (integration_steps_stars_smaller_than_4Msun and integration_steps_stars_bigger_than_4Msun)
• Removed DTD from Mannucci, Della Valle, Panagia (2006) (was deprecated in v1.2.0)
• Deprecation warnings can be silenced setting deprecation_warnings to False (it is True by default)
• Added correction of abundances data for CRI-LIM yields set
• Element production refactored: removed special case for massive stars
• Updated CNO cycle calculations
• Added yield_corrections setting to allow custom corrections for the ejections data
• Project renamed to Starmatrix

Version 1.2.0

1.2.0 (2020-03-12)

• Added Supernovas II data to the imf_supernova_rates file
• Tweak SN total energy function to make it continous
• Better docs
• Added DTD from Maoz & Graur (2017)
• The DTD from Mannucci, Della Valle & Panagia is deprecated
• Added matrix_headers setting to optionally remove headers from qm-matrices file
• The default value for binary systems fraction is now 0.15
• Added integration_step setting to set the integration step as constant in log(t) or in t
• Kroupa, Chabrier and Miller-Scalo IMFs have been slightly corrected
• Added returned_fractions setting to generate a file with the masses restored to the ISM
• Fixed: Maoz & Graur DTD rate corrected by mass
• Added new DTD: Castrillo et al. 2020

Version 1.1.0

New normalization of IMFs

• Added settings to configure IMF's mass limits: [imf_m_low, imf_m_up]
