Galaxy Evolution with Manifold Learning [PDF]
EntropyMatter in the early Universe was nearly uniform, and galaxies emerged through the gravitational growth of small primordial density fluctuations. Astrophysics has been trying to unveil the complex physical phenomena that have caused the formation and ...

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 ...

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).

Wide binary stars with non-coeval components
Open Astronomy, 2022 We have the estimated masses of components of visual binaries from their spectral classification. We have selected pairs in which the less massive component looks more evolved. Spectral observations of some of these pairs were made, and at least one pair,

The Astrophysical Journal, 2023 Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase of CMEs, as the blueshifted excess component of Balmer lines is a ...

Scaling Relations for Solar-Like Oscillations: A Review
Frontiers in Astronomy and Space Sciences, 2020 The scaling relations for solar-like oscillations provide a translation of the features of the stochastic low-degree modes of oscillation in the Sun to predict the features of solar-like oscillations in other stars with convective outer layers.

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 “Building Blocks” of Stellar Halos
Galaxies, 2017 The stellar halos of galaxies encode their accretion histories. In particular, the median metallicity of a halo is determined primarily by the mass of the most massive accreted object.

Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions
Advances in Astronomy, 2011 The dense concentration of stars and high-velocity dispersions in the Galactic center imply that stellar collisions frequently occur. Stellar collisions could therefore result in significant mass loss rates.
