MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
The temperature and chronology of heavy-element synthesis in low-mass stars
Pieter Neyskens, Sophie Van Eck, Alain Jorissen +3
Roughly half of the heavy elements (atomic mass greater than that of iron) are believed to be synthesized in the late evolutionary stages of stars with masses between 0.8 and 8 sol…
The orbits of subdwarf B + main-sequence binaries. I: The sdB+G0 system PG 1104+243
J. Vos, R. H. Östensen, P. Degroote +18
The predicted orbital period histogram of an sdB population is bimodal with a peak at short (< 10 days) and long (> 250 days) periods. Observationally, there are many short-period…
Discovery of a TiO emission band in the infrared spectrum of the S star NP Aurigae
K. Smolders, T. Verhoelst, P. Neyskens +10
We report on the discovery of an infrared emission band in the Spitzer spectrum of the S-type AGB star NP Aurigae that is caused by TiO molecules in the circumstellar environment.…
Detection of gravity modes in the massive binary V380 Cyg from Kepler spacebased photometry and high-resolution spectroscopy
A. Tkachenko, C. Aerts, K. Pavlovski +17
We report the discovery of low-amplitude gravity-mode oscillations in the massive binary star V380 Cyg, from 180 d of Kepler custom-aperture space photometry and 5 months of high-r…
The Spitzer Spectroscopic Survey of S-type Stars
K. Smolders, P. Neyskens, J. A. D. L. Blommaert +28
S-type AGB stars are thought to be in the transitional phase between M-type and C-type AGB stars. Because of their peculiar chemical composition, one may expect a strong influence…
A grid of MARCS model atmospheres for S stars
Sophie Van Eck, Pieter Neyskens, Bertrand Plez +6
S-type stars are late-type giants whose atmosphere is enriched in carbon and s-process elements because of either extrinsic pollution by a binary companion or intrinsic nucleosynth…
Abundance Patterns in S-type AGB stars : Setting Constraints on Nucleosynthesis and Stellar Evolution Models
Pieter Neyskens, Sophie Van Eck, Bertrand Plez +3
During the evolution on the AGB, S-type stars are the first objects to experience s-process nucleosynthesis and third dredge-ups, and therefore to exhibit sprocess signatures in th…
When an old star smolders: On the detection of hydrocarbon emission from S-type AGB stars
K. Smolders, B. Acke, T. Verhoelst +8
Polycyclic aromatic hydrocarbons (PAHs) produce characteristic infrared emission bands that have been observed in a wide range of astrophysical environments, where carbonaceous mat…
