The White Dwarf Initial-Final Mass Relation for Progenitor Stars From 0.85 to 7.5 M
Jeffrey D. Cummings, Jason S. Kalirai, P. -E. Tremblay +2
We present the initial-final mass relation (IFMR) based on the self-consistent analysis of Sirius B and 79 white dwarfs from 13 star clusters. We have also acquired additional sign…
Star Cluster Ages in the Gaia Era
Jieun Choi, Charlie Conroy, Yuan-Sen Ting +3
We use the framework developed as part of the MESA Isochrones and Stellar Tracks (MIST) project to assess the utility of several types of observables in jointly measuring the age a…
On the Red Giant Branch: Ambiguity in the Surface Boundary Condition Leads to ~100 K Uncertainty in Model Effective Temperatures
Jieun Choi, Aaron Dotter, Charlie Conroy +1
The effective temperature (Teff) distribution of stellar evolution models along the red giant branch (RGB) is sensitive to a number of parameters including the overall metallicity,…
Age Determinations of the Hyades, Praesepe, and Pleiades via MESA Models with Rotation
Seth Gossage, Charlie Conroy, Aaron Dotter +4
The Hyades, Praesepe, and Pleiades are well studied stellar clusters that anchor important secondary stellar age indicators. Recent studies have shown that main sequence turn off-b…
The Revolution Revolution: magnetic morphology driven spin-down
C. Garraffo, J. J. Drake, A. Dotter +6
Observations of young open clusters show a bimodal distribution of rotation periods that has been difficult to explain with existing stellar spin-down models. Detailed MHD stellar…
