Ages of the resolved stellar populations inside the JWST/MIRI bubbles in NGC 628
Avinash Ck, Divakara Mayya, Alessandro Bressan +3
JWST images in the MIRI filters are characterized by prominent interstellar bubbles, most of which are expected to be created by mechanical energy injected into the interstellar me…
The Local Ultraviolet to Infrared Treasury II. Refining Star Formation Histories of Ten Metal-Poor Dwarf Galaxies with Simultaneous UV-Optical Two-CMD Fitting
Yumi Choi, Karoline M. Gilbert, Benjamin F. Williams +10
We present the star formation histories (SFHs) of ten metal-poor (<12% Zsun), star-forming dwarf galaxies from the Local Ultraviolet to Infrared Treasury (LUVIT) survey. The derive…
Discovery of astrometric accelerations by dark companions in the globular cluster Centauri
Imants Platais, Johannes Sahlmann, Leo Girardi +6
We present results from the search for astrometric accelerations of stars in Centauri using 13 years of regularly-scheduled {\it Hubble Space Telescope} WFC3/UVIS calibration o…
The JWST Resolved Stellar Populations Early Release Science Program IV: The Star Formation History of the Local Group Galaxy WLM
Kristen. B. W. McQuinn, Max J. B. Newman, Alessandro Savino +23
We present the first star formation history (SFH) and age-metallicity relation (AMR) derived from resolved stellar populations imaged with the JWST NIRCam instrument. The target is…
Is there a metallicity ceiling to form carbon stars? - A novel technique reveals a scarcity of C stars in the inner M31 disk
M. L. Boyer, L. Girardi, P. Marigo +10
We use medium-band near-infrared (NIR) Hubble Space Telescope WFC3 photometry with model NIR spectra of Asymptotic Giant Branch (AGB) stars to develop a new tool for efficiently di…
Dwarf Elliptical Galaxies: Structure, Star Formation, and Color-Magnitude Diagrams
G. Carraro, C. Chiosi, L. Girardi +1
The aim of this paper is to cast light on the formation and evolution of elliptical galaxies by means of N-body/hydro-dynamical simulations that include star formation, feed-back a…
The evolution of the V-K colours of single stellar populations
Leo Girardi, Gianpaolo Bertelli
We discuss how the integrated V-K colours of single stellar populations evolve with age and metallicity. Some of the uncertainties associated to the properties of the underlying st…
