Euclid: Early Release Observations -- Internal kinematics and the convective-transition gap of NGC 6397

M. Griggio, M. Libralato, R. Gerasimov +130

We present a 'multiple-pass' data-reduction tool designed for Euclid, based on software developed for the Hubble Space Telescope (HST), which improves the astrometric and photometr…

Mid-infrared JWST spectra of carbon stars in the Large Magellanic Cloud

G. C. Sloan, B. Aringer, Kathleen E. Kraemer +11

Mid-infrared spectra from the Medium Resolution Spectrometer on the James Webb Space Telescope have revealed the molecular chemistry of carbon stars in the Large Magellanic Cloud w…

Central-star extinctions towards planetary nebulae

Alexander Csukai, Albert A. Zijlstra, Iain McDonald +1

Planetary nebulae trace the hottest and most luminous phase of evolution of solar-type stars. We use these hot, bright stars to investigate extinctions towards a complete sample of…

PySSED: an automated method of collating and fitting stellar spectral energy distributions

Iain McDonald, Albert A. Zijlstra, Nick L. J. Cox +4

Stellar atmosphere modelling predicts the luminosity and temperature of a star, together with parameters such as the effective gravity and the metallicity, by reproducing the obser…

ATOMIUM: Halide molecules around the S-type AGB star W Aquilae

T. Danilovich, M. Van de Sande, J. M. C. Plane +36

S-type asymptotic giant branch (AGB) stars are thought to be intermediates in the evolution of oxygen- to carbon-rich AGB stars. The chemical compositions of their circumstellar en…

Circumstellar CO J = 3-2 detected around the evolving metal-poor ([Fe/H] ~ -1.15 dex) AGB star RU Vulpeculae

Iain McDonald, Stefan Uttenthaler, Albert A. Zijlstra +2

We report the first detection of CO J = 3-2 around a truly metal-poor evolved star. RU Vulpeculae is modelled to have Teff ~ 3620 K, L ~ 3128 +/- 516 L_Sun, log(g) = 0.0 ~ 0.2 dex…

ALMA observations of the nearby AGB star L2 Puppis - I. Mass of the central star and detection of a candidate planet

P. Kervella, W. Homan, A. M. S. Richards +4

Six billion years from now, while evolving on the asymptotic giant branch (AGB), the Sun will metamorphose from a red giant into a beautiful planetary nebula. This spectacular evol…

Herschel Planetary Nebula Survey (HerPlaNS) - First Detection of OH+ in Planetary Nebulae

I. Aleman, T. Ueta, D. Ladjal +15

We report the first detections of OH emission in planetary nebulae (PNe). As part of an imaging and spectroscopy survey of 11 PNe in the far-IR using the PACS and SPIRE instrum…

The Herschel Planetary Nebula Survey (HerPlaNS) I. Data Overview and Analysis Demonstration with NGC 6781

T. Ueta, D. Ladjal, K. M. Exter +30

This is the first of a series of investigations into far-IR characteristics of 11 planetary nebulae (PNs) under the Herschel Space Observatory Open Time 1 program, Herschel Planeta…

Detailed Abundances for a Large Sample of Giant Stars in the Globular Cluster 47 Tucanae (NGC 104)

Maria J. Cordero, Catherine A. Pilachowski, Christian I. Johnson +3

47 Tuc is an ideal target to study chemical evolution and GC formation in massive more metal-rich GCs since is the closest, massive GC. We present chemical abundances for O, Na, Al…
