Stellar coronal mass ejections [PDF]
Serbian Astronomical Journal, 2022 Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect ...

The Astrophysical Journal, 2023 In this empirical work, we aim to quantify the systematic uncertainties in stellar-mass ( M _⋆ ) estimates made from spectral energy distribution (SED) fitting through stellar population synthesis (SPS) for galaxies in the local Universe by using the ...

Stellar Mass Calibrations for Local Low-mass Galaxies
The Astrophysical JournalThe stellar masses of galaxies are measured from integrated light via several methods—however, few of these methods were designed for low-mass ( M _⋆ ≲ 10 ^8 M _⊙ ) “dwarf” galaxies, whose properties (e.g., stochastic star formation, low metallicity ...

Dependence of Planet Populations on Stellar Mass and Metallicity: A Pebble-accretion-based Planet Population Synthesis Model [PDF]
The Astrophysical JournalThe formation and evolution of planetary systems are linked to their host stellar environment. In this study, we employ a pebble-accretion-based planet population synthesis model to explore the correlation between planetary properties and stellar mass ...

Variation in the stellar mass function along stellar streams [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Stellar streams are the inevitable end product of star cluster evolution, with the properties of a given stream being related to its progenitor. We consider how the dynamical history of a progenitor cluster, as traced by the evolution of its stellar mass function, is reflected in the resultant stream.

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).

Stellar mass as the ‘glocal’ driver of galaxies’ stellar population properties [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The properties of the stellar populations in a galaxy are known to correlate with the amount and the distribution of stellar mass. We take advantage of the maps of light-weighted mean stellar age $\mathit {\mathrm{ Age}_{\mathrm{ wr}}}$ and metallicity $\mathit {\mathrm{ Z}_{*\mathrm{ wr}}}$ for a sample of 362 galaxies from the

The Chocolate Chip Cookie Model: Dust-to-metal Ratio of H ii Regions
The Astrophysical Journal Letters, 2023 Using a sample of face-on star-forming galaxies selected from the Sloan Digital Sky Survey, we statistically derive the typical optical depth τ _cl of individual H ii regions based on the “Chocolate Chip Cookie” model of Lu et al. (2022).

THE MASS DISTRIBUTION OF STELLAR-MASS BLACK HOLES [PDF]
The Astrophysical Journal, 2011 We perform a Bayesian analysis of the mass distribution of stellar-mass black holes using the observed masses of 15 low-mass X-ray binary systems undergoing Roche lobe overflow and five high-mass, wind-fed X-ray binary systems. Using Markov Chain Monte Carlo calculations, we model the mass distribution both parametrically---as a power law, exponential,
