Tidal Dwarf Galaxies [PDF]

open access: yesHighlights of Astronomy, 1998
The life and evolution of galaxies are dramatically affected by environmental effects. Interactions with the intergalactic medium and collisions with companions cause major perturbations in the morphology and contents of galaxies: in particular stars and gas clouds may be gravitationally pulled out from their parent galaxies during tidal encounters ...

Uncovering blue diffuse dwarf galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Extremely metal poor (XMP) galaxies are known to be very rare, despite the large numbers of low-mass galaxies predicted by the local galaxy luminosity function. This paper presents a sub-sample of galaxies that were selected via a morphology-based search on SDSS images with the aim of finding these elusive XMP galaxies. By using the recently discovered

Dwarf elliptical galaxies

open access: yesThe Astrophysical Journal, 1983
We propose that dwarf elliptical galaxies are the bound remnants of more massive stellar systems, such as a parent galaxy which has lost more than half its mass in gas ejection during a burst of star formation, or an unbound tidal debris produced during the interaction of two giant galaxies.

ANGULAR MOMENTUM OF DWARF GALAXIES [PDF]

The Pristine dwarf galaxy survey–V. The edges of the dwarf galaxy Hercules

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT We present a new spectroscopic study of 175 stars in the vicinity of the dwarf galaxy Hercules (d ∼ 132 kpc) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Field multi-object system to solve the conundrum that whether Hercules is tidally disrupting.

Dust in Nearby DWARF Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1994
The aim of the present paper is to look for the gas-to-dust ratio in different types of galaxies and for a correlation between this ratio and the metallicity in dwarf galaxies. The recent compilation of data on nearby galaxies by Schmidt & Boller (1992, hereinafter SB) including HI and dust ...

PERICLES: A Set of Empirical Rotational Isochrones Modeled on Cool Dwarfs in Open Clusters and Wide Binaries

open access: yesAstronomische Nachrichten, Volume 347, Issue 1, January 2026.
ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.
