Evolutionary synthesis of stellar populations: a modular tool [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
A new tool for the Evolutionary Synthesis of Stellar Populations (EPS) is presented, which is based on three independent matrices, giving respectively: 1) the fuel consumption during each evolutionary phase as a function of stellar mass; 2) the typical ...

Stellar-mass black holes in young massive and open stellar clusters – IV. Updated stellar-evolutionary and black hole spin models and comparisons with the LIGO-Virgo O1/O2 merger-event data [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT I present a set of long-term, direct, relativistic many-body computations of model dense stellar clusters with up-to-date stellar-evolutionary, supernova (SN), and remnant natal-kick models, including pair instability and pulsation pair instability supernova (PSN and PPSN), using an updated version of ${\rm{\small NBODY7}}$  N ...

The Ages of Galactic Bulge Stars with Realistic Uncertainties

open access: yesThe Astrophysical Journal, 2023
Using modern isochrones with customized physics and carefully considered statistical techniques, we recompute the age distribution for a sample of 91 microlensed dwarfs in the Galactic bulge presented by Bensby et al.

Modules for Experiments in Stellar Astrophysics (MESA): Time-dependent Convection, Energy Conservation, Automatic Differentiation, and Infrastructure

open access: yesThe Astrophysical Journal Supplement Series, 2023
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics ( MESA ). The new auto _ diff module implements automatic differentiation in MESA , an enabling capability that alleviates the need for ...

Astrophysical Properties of 600 Bona Fide Single Stars in the Hyades Open Cluster

open access: yesThe Astronomical Journal, 2023
The determination of the astrophysical properties of stars remains challenging and frequently relies on the application of stellar models. Stellar sequences in nearby open clusters provide some of the best means to test and calibrate stellar evolutionary

Aluminium-26 from Massive Binary Stars. III. Binary Stars up to Core Collapse and Their Impact on the Early Solar System

open access: yesThe Astrophysical Journal, 2023
Many of the short-lived radioactive nuclei that were present in the early solar system can be produced in massive stars. In the first paper in this series, we focused on the production of ^26 Al in massive binaries.

PRE-MAIN SEQUENCE EVOLUTIONS OF SOLAR ABUNDANCE LOW MASS STARS [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2007
We present the Pre-Main Sequence (PMS) evolutionary tracks of stars with 0.065~5.0M_⨀. The models were evolved from the PMS stellar birthline to the onset of hydrogen burning in the core.

Influence of the initial orbital period and accretion efficiency on the low-mass binary evolution [PDF]

open access: yesSerbian Astronomical Journal, 2021
This paper presents detailed evolutionary models of low-mass binary systems (1.25 + 1 M⊙) with initial orbital periods of 10, 50 and 100 days and accretion efficiency of 10%, 20%, 50%, and a conservative assumption.
