wd_acc_small_dm — MESA r23.05.1 documentation
Jul 22, 2020 · This test checks accretion in MESA with small timesteps, such that the mass added in the step is similar to the mass of the outer zone. The accreted material has a different composition (H/He mixture) than the initial composition of the WD surface (pure H).
Stretching of the Basin and Range and Lifting of the Colorado …
Feb 7, 2023 · It is made of colorful sedimentary and metamorphosed rocks that have been deposited over 1.7 billion years. The lowest levels, such as Vishnu Schist, were scraped off a subducting plate and scrunched onto (accreted) to North America from ocean plate subduction.
Test suite — MESA r22.05.1 documentation - docs.mesastar.org
Your first stop when setting up a new problem with MESA should be the MESA test suite. You will find a wide range of sample cases there. Looking at the test_suite inlists is a quick way to familiarize yourself with the set of options relevant to your problem.
[mesa-users] Angular momentum for accreted material | mesa - SourceForge
Hi. I'm trying to implement rotational spinup of a star due to accretion, increase it's total angular momentum. Checking on adjust_mass.f, I found. s% omega(k) = s% omega(s% k_below_recently_added) s% j_rot(k) = s% omega(k)*s% i_rot(k) rotating with the rotational speed of material just below it. If I want to.
[1210.5209] MESA Models of Classical Nova Outbursts: The …
Oct 18, 2012 · In this paper we use the MESA stellar evolution code to construct multicycle nova evolution sequences with CO WD cores. We explore a range of WD masses and accretion rates as well as the effect of different cooling times before the onset of accretion.
The accreted helium on the WD inevitably undergoes a thermonuclear instability, causing a detonation that is expected to transition into the WD core and lead to a thermonuclear supernova while the donor orbits nearby with high velocity.
[2006.01827] Hydrodynamic Simulations of Classical Novae; CO …
Jun 2, 2020 · We report on 3 studies in this paper. First, simulations in which we accrete only solar matter using NOVA (our 1-D, fully implicit, hydro code). Second, we use MESA for similar studies in which we accrete only Solar matter and compare the results.
Intra-oceanic subduction shaped the assembly of Cordilleran ... - Nature
Apr 3, 2013 · A new explanation for the origin of the accreted terranes that form the mountainous Cordillera of western North America is proposed and tested: stationary, intra-oceanic subduction deposited ...

Sep 21, 2015 · A new MESA capability to calculate weak reaction rates "on-the-fly" from input nuclear data allows better simulation of accretion induced collapse of massive white dwarfs and the fate of some massive stars.
