Homogeneous Photometry VI: Variable Stars in the Leo I Dwarf Spheroidal Galaxy [PDF]

open access: yes, 2014
From archival ground-based images of the Leo I dwarf spheroidal galaxy, we have identified and characterized the pulsation properties of 164 candidate RR Lyrae variables and 55 candidate anomalous and/or short-period Cepheids.

Metallicity gradients in the Sagittarius dwarf spheroidal galaxy [PDF]

open access: yesAstronomy & Astrophysics, 2001
Metallicity gradients in the Sagittarius dwarf Galaxy (Sgr) are investigated by using infrared photometric data from the 2MASS survey. To search for metallicity effects, the giant branch in a field situated near the Center of the Sgr is compared to the giant branch in a field situated near its southern edge.

Implications of elemental abundances in dwarf spheroidal galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2006
Unusual elemental abundance patterns observed for stars belonging to nearby dwarf spheroidal (dSph) galaxies are discussed. Analysis of the [alpha/H] vs. [Fe/H] diagrams where alpha represents Mg or average of alpha-elements reveals that Fe from Type Ia supernovae (SNe Ia) does not contribute to the stellar abundances in the dSph galaxies where the ...

STELLAR KINEMATICS OF THE ANDROMEDA II DWARF SPHEROIDAL GALAXY [PDF]

open access: yesThe Astrophysical Journal, 2012
We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy Andromeda II (And II) based on Keck DEIMOS spectroscopy of 531 red giant branch stars.

Dependence of stellar substructures in M31 type galaxy on satellite morphology in galaxy mergers [PDF]

open access: yesSerbian Astronomical Journal, 2022
Stellar streams and shells are observed in halos of spiral galaxies. In this paper, we investigated the formation of these structures due to mergers between the host spiral galaxy and its dwarf satellite galaxies.

Asymptotic giant branch stars in the Sculptor dwarf spheroidal galaxy [PDF]

open access: bronze, 2011
JHK_S photometry is presented for a 35 arcmin square field centred on the Sculptor dwarf spheroidal galaxy. With the aid of published kinematic data definite galaxy members are identified and the width in J-K of the colour-magnitude diagram is shown to ...

Multiple chemodynamic stellar populations of the Ursa Minor dwarf spheroidal galaxy [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data without the assumption of spherical symmetry.
