Evolution of the Stellar Mass--Metallicity Relation - I: Galaxies in the z~0.4 Cluster Cl0024 [PDF]

, 2018
We present the stellar mass-stellar metallicity relationship (MZR) in the Cl0024+1654 galaxy cluster at z~0.4 using full spectrum stellar population synthesis modeling of individual quiescent galaxies. The lower limit of our stellar mass range is $M_*=10^

A Review of the Mixing Length Theory of Convection in 1D Stellar Modeling

Galaxies, 2023
We review the application of the one-dimensional Mixing Length Theory (MLT) model of convection in stellar interiors and low-mass stellar evolution.

Updated High-temperature Opacities for the Dartmouth Stellar Evolution Program and Their Effect on the Jao Gap Location

The Astrophysical Journal, 2023
The Jao Gap, a 17% decrease in stellar density at M _G ∼ 10 identified in both Gaia Data Release 2 and Early Data Release 3, presents a new method to probe the interior structure of stars near the fully convective transition mass.

Linking the formation and fate of exo-Kuiper belts within solar system analogues [PDF]

, 2020
Escalating observations of exo-minor planets and their destroyed remnants both passing through the solar system and within white dwarf planetary systems motivate an understanding of the orbital history and fate of exo-Kuiper belts and planetesimal discs.

Effects of thermohaline instability and rotation-induced mixing on the evolution of light elements in the Galaxy : D, 3He and 4He [PDF]

, 2012
Recent studies of low- and intermediate-mass stars show that the evolution of the chemical elements in these stars is very different from that proposed by standard stellar models.

POSYDON: A General-purpose Population Synthesis Code with Detailed Binary-evolution Simulations

The Astrophysical Journal Supplement Series, 2023
Most massive stars are members of a binary or a higher-order stellar system, where the presence of a binary companion can decisively alter their evolution via binary interactions. Interacting binaries are also important astrophysical laboratories for the

The Mass-Metallicity and Luminosity-Metallicity Relation from DEEP2 at z ~ 0.8 [PDF]

, 1995
We present the mass-metallicity (MZ) and luminosity-metallicity (LZ) relations at z ~ 0.8 from ~1350 galaxies in the Deep Extragalactic Evolutionary Probe 2 (DEEP2) survey.

Rotation and stellar evolution

EPJ Web of Conferences, 2013
The effects of rotation on the evolution and properties of low-mass stars are first discussed from the pre-main sequence to the red giant phase. We then briefly indicate how some observational constraints available for these stars can help us progress in

Pulsation Period Change & Classical Cepheids: Probing the Details of Stellar Evolution

, 2014
Measurements of secular period change probe real-time stellar evolution of classical Cepheids making these measurements powerful constraints for stellar evolution models, especially when coupled with interferometric measurements. In this work, we present
