The Tucana dwarf spheroidal galaxy: not such a massive failure after all [PDF]

open access: yesAstronomy & Astrophysics, 2020
Context. Isolated local group (LG) dwarf galaxies have evolved most or all of their life unaffected by interactions with the large LG spirals and therefore offer the opportunity to learn about the intrinsic characteristics of this class of objects. Aims.

The chemical evolution of the dwarf spheroidal galaxy Sextans [PDF]

open access: yesAstronomy & Astrophysics, 2019
We present our analysis of the FLAMES dataset targeting the central 25′ region of the Sextans dwarf spheroidal galaxy (dSph). This dataset is the third major part of the high-resolution spectroscopic section of the ESO large program 171.B-0588(A ...

Chemical feature of Eu abundance in the Draco dwarf spheroidal galaxy [PDF]

open access: bronze, 2015
Chemical abundance of r-process elements in nearby dwarf spheroidal (dSph) galaxies is a powerful tool to probe the site of r-process since their small-mass scale can sort out individual events producing r-process elements.

A Deep View into the Nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. I. Data and Stellar Population Characterization [PDF]

open access: bronzeAstrophysical Journal, 2019
The center of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) hosts a nuclear star cluster (NSC), M54, which is the only galaxy nucleus that can be resolved into individual stars at optical wavelengths.

Kinematics and Metallicity of the Dwarf Spheroidal Galaxy Andromeda XVIII

open access: goldThe Astrophysical Journal
Andromeda XVIII is an isolated dwarf galaxy 579 kpc away from the nearest large galaxy, M31. It is a candidate “backsplash galaxy” that might have been affected by a close passage to M31.

Enrichment in r-process Elements from Multiple Distinct Events in the Early Draco Dwarf Spheroidal Galaxy* [PDF]

open access: hybrid, 2017
The stellar record of elemental abundances in satellite galaxies is important to identify the origin of r-process because such a small stellar system could have hosted a single r-process event, which would distinguish member stars that are formed before ...

Faint Stars in a Faint Galaxy. II. The Low-mass Stellar Initial Mass Function of the Boötes I Ultrafaint Dwarf Spheroidal Galaxy [PDF]

open access: goldThe Astrophysical Journal, 2022
This paper presents improved constraints on the low-mass stellar initial mass function (IMF) of the Boötes I (Boo I) ultrafaint dwarf galaxy, based on our analysis of recent deep imaging from the Hubble Space Telescope.

Zinc in the Sculptor dwarf spheroidal galaxy [PDF]

open access: yesAstronomy & Astrophysics, 2017
From ESO VLT/FLAMES/GIRAFFE spectra, abundance measurements of Zn have been made in $\approx$100 individual red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy.

Spatial dependence of the star formation history in the central regions of the Fornax dwarf spheroidal galaxy [PDF]

open access: bronze, 2013
We present the Star Formation History (SFH) and the age-metallicity relation (AMR) in three fields of the Fornax dwarf spheroidal galaxy. They sample a region spanning from the centre of the galaxy to beyond one core radius, which allows studying ...
