Inlists of Published Results

We encourage posting enough information (inlists, run_star_extras, mod files, etc) for an experienced MESA user to reproduce the results of your published papers. Doing this is one way that you can give back to the MESA community and help deliver on the hopes expressed in the MESA Manifesto that Open Source will be matched with Open Knowledge. This is the place to share your insights so that the next researcher can build on what you did (and cite your work!) instead of reinventing the wheel. Maybe collectively we can then solve more problems in stellar astrophysics more efficiently.

Rotating 80 Msun zero metallicity model (Omega/Omega_crit at ZAMS = 0.5)

This folder contains the inlist and model files used for the full evolution of a rotating and magnetic 80 Msun, zero metallicity star. The initial ZAMS rotation of the star is taken to be 50% of the critical Keplerian value. This model and other similar models were originally presented in Chatzopoulos & Wheeler (2012).

epsilon-Mechanism Triggering Gravity Modes in Rigel?

Based on a consistent models calculated by MESA, we could explain the observed long-period variabilities in Rigel (and possibly other BA-type supergiants) in terms of g-modes destabilized by epsilon-mechanism.

The stability of massive main-sequence stars as a function of metallicity

"The stability of massive main-sequence stars as a function of metallicity" by Joshua H. Shiode, Eliot Quataert, & Phil Arras (2012). Pulished in MNRAS, vol. 423, p. 3397-3404 This folder contains inlists and pre-MS models used to create models of 120 -- 1000 solar mass, Population III, non-rotating stellar models evolved from ZAMS to center hydrogen mass fraction of 0.4 (stopped before TAMS due to difficulties evolving the highly radiation-dominated stellar envelope).

Effects of Rotationally-Induced Mixing in Compact Binary Systems with Low-Mass Secondaries and in Single Solar-Type Stars folder

Chatzopoulos, Robinson & Wheeler 2012 This folder contains the inlist and model files used for the full evolution of a rotating and magnetic 1.2 Msun, solar metallicity star. The initial ZAMS rotation of the star is taken to be 30% of the critical Keplerian value. This model and other similar models were originally presented in Chatzopoulos, Robinson & Wheeler (2012) which is accepted for publication in the Astrophysical Journal.

The Compactness of Presupernova Stellar Cores

We have studied the compactness of presupernova stars using full star and bare CO core models with MESA (v.4930) evolved from ZAMS until the core oxygen depletion. Note that some of the features in the inlists don't work with the newer version of the code (i.e. Buchmann, CF88 rates).

On Carbon Burning in Super Asymptotic Giant Branch Stars

We model carbon flames in 2755 SAGB MESA models. We derive an analytic expression for the location of the flame's ignition. We also show that rotation has little impact on the flame, while overshoot has a large impact due to its effect on the size of the CO core formed. Farmer, Fields & Timmes, ApJ, 2015.

Capella (α Aurigae) Revisited: New Binary Orbit, Physical Properties, and Evolutionary State

Torres, Guillermo; Claret, Antonio; Pavlovski, Krešimir; Dotter, Aaron

Knowledge of the chemical composition and absolute masses of Capella are key to understanding the evolutionary state of this benchmark binary system comprising two giant stars. Previous efforts, including our own 2009 study, have largely failed to reach an acceptable agreement between the observations and current stellar evolution models, preventing us from assessing the status of the primary. Here we report a revision of the physical properties of the components incorporating recently published high-precision radial velocity measurements, and a new detailed chemical analysis providing abundances for more than 20 elements in both stars. We obtain highly precise (∼0.3%) masses of 2.5687 ± 0.0074 {M}ȯ and 2.4828 ± 0.0067 {M}ȯ , radii of 11.98 ± 0.57 {R}ȯ and 8.83 ± 0.33 {R}ȯ , effective temperatures of 4970 ± 50 and 5730 ± 60 K, and independently measured luminosities based on the orbital parallax (78.7 ± 4.2 {L}ȯ and 72.7 ± 3.6 {L}ȯ ). We find an excellent match to stellar evolution models at the measured composition of [{Fe}/{{H}}]=-0.04+/- 0.06. Three different sets of models place the primary star firmly at the end of the core helium-burning phase (clump), while the secondary is known to be evolving rapidly across the Hertzprung gap. The measured lithium abundance, the C/N ratio, and the 12C/13C isotopic carbon abundance ratio, which change rapidly in the giant phase, are broadly in agreement with expectations from models. Predictions from tidal theory for the spin rates, spin–orbit alignment, and other properties do not fare as well, requiring a 40-fold increase in the efficiency of the dissipation mechanisms in order to match the observations.
