The Treasury of Extremely Metal-Poor O Stars

O. Grace Telford, Christiana Erba, Kristen B. W. McQuinn +10

The Treasury of Extremely Metal-Poor O Stars (TEMPOS) is a Hubble Space Telescope survey of hot and massive O-type stars in nearby, low-metallicity galaxies (20% of the s…

Ionized Nebulae Around Two New Symbiotic Stars: GR Cygni and [D75] 141

Howard E. Bond, Calvin Carter, Sven E. Eklund +4

In the course of selecting targets for a spectroscopic survey of faint planetary-nebula nuclei, we encountered two anomalous cases of late-type variable stars surrounded by nebulos…

SPIRITS 19q: Dust Production by a Subsolar-metallicity Carbon-rich Wolf-Rayet Star in NGC 2403

Sam Rose, Ryan M. Lau, Jacob E. Jencson +20

We present JWST/NIRSpec IFU observations of SPIRITS 19q, the highly dust-producing carbon-rich (WC) binary candidate located in a subsolar-metallicity region of the nearby spiral g…

Physics of Eclipsing Binaries. VI. Hot, compact stars

David Jones, Nicole Reindl, Kyle Conroy +9

Models of eclipsing binaries require the assignment of appropriate emergent intensities to the surface elements of the binary components. For distance-dependent modelling of flux-c…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…

OH/IR stars in the inner Galactic bulge: I. Colour, CO line, and stellar light curve characteristics

H. Olofsson, T. Khouri, S. Muller +11

Stars on the asymptotic giant branch (AGB) play important roles in a number of astronomical contexts. To quantify these roles, it is necessary to establish the mass-loss characteri…
