vice.yields.sneia.single¶
Lookup the mass yield of a given element from a single instance of a type Ia supernova (SN Ia) as determined by a specified study and explosion model.
Signature: vice.yields.sneia.single(element, study = “seitenzahl13”, model = “N1”)
Parameters¶
- element
str[case-insensitive] The symbol of the element to look up the yield for.
- study
str[case-insensitive] [default“seitenzahl13”] A keyword denoting which study to adopt the yield from
Keywords and their Associated Studies:
- model
str[case-insensitive] [defaultN1] A keyword denoting the explosion model from the associated study to adopt.
Keywords and their Associated Models:
“seitenzahl13” : N1, N3, N5, N10, N20, N40, N100H, N100, N100L, N150, N200, N300C, N1600, N1600C, N100_Z0.5, N100_Z0.1, N100_Z0.01
“iwamoto99” : W7, W70, WDD1, WDD2, WDD3, CDD1, CDD2
Returns¶
- yreal number
The mass yield of the given element in \(M_\odot\) under the specified explosion model as reported by the nucleosynthesis study.
Raises¶
- ValueError
The element is not built into VICE
The study is not built into VICE
- LookupError
The study is recognized, but the model is not recognized for that particular study.
- IOError [Occurs only if VICE’s file structure has been modified]
The data file is not found.
Notes¶
The data stored in this module are reported for each corresponding study as published. The Seitenzahl et al. (2013) model reported mass yields after complete decay of all radioactive nuclides with half-lives less than 2 Gyr, and the Iwamoto et al. (1999) study fully decayed all unstable isotopes; any additional treatment for radioactive isotopes is thus unnecessary.
