Galaxies, 2020 Luminous Blue Variables are massive evolved stars, here we introduce this outstanding class of objects. Described are the specific characteristics, the evolutionary state and what they are connected to other phases and types of massive stars. Our current

Stellar populations with ELTs [PDF]
Proceedings of the International Astronomical Union, 2005 The star formation, mass assembly and chemical enrichment histories of galaxies, and their present distributions of dark matter, remain encoded in their stellar populations. Distinguishing the actual distribution functions of stellar age, metallicity and kinematics at several locations in a range of galaxies, sampling across Hubble types and ...

The Auriga stellar haloes: connecting stellar population properties with accretion and merging history [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We examine the stellar haloes of the Auriga simulations, a suite of 30 cosmological magnetohydrodynamical high-resolution simulations of Milky Way-mass galaxies performed with the moving-mesh code arepo.

A Hierarchical Bayesian Framework for Inferring the Stellar Obliquity Distribution
The Astronomical Journal, 2023 Stellar obliquity, the angle between a planet’s orbital axis and its host star’s spin axis, traces the formation and evolution of a planetary system. In transiting-exoplanet observations, only the sky-projected stellar obliquity can be measured, but this

Evidence for the Third Stellar Population in the Milky Way’s Disk [PDF]
Astrophysical Journal, 2019 The Milky Way is a unique laboratory in which stellar properties can be measured and analyzed in detail. In particular, stars in the older populations encode information on the mechanisms that led to the formation of our Galaxy.

A Study of Primordial Very Massive Star Evolution
The Astrophysical Journal, 2023 We present new evolutionary models of primordial very massive stars with initial masses ranging from 100 to 1000 M _⊙ that extend from the main sequence to the onset of dynamical instability caused by the creation of electron–positron pairs during core C,

Metal-rich, Metal-poor: Updated Stellar Population Models for Old Stellar Systems [PDF]
, 2018 We present updated stellar population models appropriate for old ages (>1 Gyr) and covering a wide range in metallicities (−1.5 ≲ [Fe/H] ≲ 0.3). These models predict the full spectral variation associated with individual element abundance variation as a ...

Stellar population of Sco OB2 revealed by Gaia DR2 data [PDF]
Astronomy & Astrophysics, 2018 Context. The Sco OB2 association is the nearest OB association, extending over approximately 2000 square degrees on the sky. Only its brightest and most massive members are already known (from HIPPARCOS) across its entire size, while studies of its lower

LATIS: The Stellar Mass–Metallicity Relation of Star-forming Galaxies at z ∼ 2.5
The Astrophysical Journal, 2023 We present the stellar mass–stellar metallicity relation for 3491 star-forming galaxies at 2 ≲ z ≲ 3 using rest-frame far-ultraviolet spectra from the Ly α Tomography IMACS Survey (LATIS).
