A normalizing flow approach for the inference of star cluster properties from unresolved broadband photometry I: Comparison to spectral energy distribution fitting

Daniel Walter, Victor F. Ksoll, Ralf S. Klessen +8

Estimating properties of star clusters from unresolved broadband photometry is a challenging problem that is classically tackled by spectral energy distribution (SED) fitting metho…

Evolved Supergiants in PHANGS I: Red Supergiants in 19 Galaxies between 5-20 Mpc with HST and JWST

Sumit K. Sarbadhicary, David Thilker, Adam K. Leroy +17

Red supergiants (RSGs) are important for our understanding of supernova progenitors, stellar populations, stellar evolution, mass loss and dust production. Extragalactic surveys of…

PAH Marks the Spot: Digging for Buried Clusters in Nearby Star-forming Galaxies

Gabrielle B. Graham, Daniel A. Dale, Chase L. Smith +39

The joint capabilities of the Hubble Space Telescope (HST) and JWST allow for an unparalleled look at the early lives of star clusters at near- and mid-infrared wavelengths. We pre…

Isolated massive star candidates in NGC 4242 with GULP

Pietro Facchini, Eva K. Grebel, Anna Pasquali +16

There is considerable debate on how massive stars form, including whether a high-mass star must always form with a population of low-mass stars or whether it ca…

CLASSY XII: Nitrogen Enrichment Shaped by Gas Density and Feedback

Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +25

We investigate the chemical evolution of N/O using a sample of 45 local star-forming galaxies (SFGs) from the CLASSY survey. This sample spans a wide range of galaxy properties, wi…

Very Massive Stars with the Habitable Worlds Observatory

Fabrice Martins, Aida Wofford, Miriam Garcia +3

Very massive stars (VMS) are defined as stars with an initial mass in excess of 100 Msun. Because of their short lifetime and the shape of the stellar mass function, they are rare…
