The tidal features of the classical Milky Way satellites: Expected in MOND but inconsistent with cold dark matter models
Elena Asencio, Indranil Banik, Pavel Kroupa
Most classical satellites of the Milky Way are known to display signs of tidal disturbance (e.g. tidal tails, substructures, and distorted shapes). This cannot be explained by the…
The fingerprint of primordial mass segregation on the tidal tails of star clusters
S. Mojtaba Ghasemi, Hosein Haghi, Mohammad Mansoury +3
We investigate the effect of primordial mass segregation (PMS) in shaping the tidal tail structures of star clusters, searching for any trace of PMS on the tails at both early and…
Intermediate-Mass Mergers: A New Scenario for Several FS CMa Stars
Daniela Korcakova, Nela Dvorakova, Iris Bermejo Lozano +6
We summarise the properties and nature of a peculiar group of B-type stars called FS CMa stars. These stars show the B[e] phenomenon, i.e., their spectra exhibit both forbidden emi…
The MOND Depth Index and Dynamical Maturity Clock: Toward a Universal Classification of Galaxies and Star Clusters
Robin Eappen, Pavel Kroupa
Mass discrepancies in galaxies are empirically known to appear only below a characteristic acceleration scale a0. Here we show that this behaviour is not limited to galaxies: it ex…
Dynamical Friction Constraints on the Dark Matter Hypothesis Across Astronomical Scales
X. Hernandez, Pavel Kroupa
Dynamical friction implies a consistency check on any system where dark matter particles are hypothesised to explain orbital dynamics requiring more mass under Newtonian gravity th…
Model-Independent Inference of Galaxy Star Formation Histories in the Local Volume
Robin Eappen, Pavel Kroupa
Understanding the diversity of star formation histories (SFHs) of galaxies is key to reconstructing their evolutionary paths. Traditional models often assume parametric forms such…
