Searching for Biosignatures in Exoplanetary Impact Ejecta
Gianni Cataldi, Alexis Brandeker, Philippe Thébault +5
With the number of confirmed rocky exoplanets increasing steadily, their characterisation and the search for exoplanetary biospheres is becoming an increasingly urgent issue in ast…
ALMA resolves CI emission from the Pictoris debris disk
Gianni Cataldi, Alexis Brandeker, Yanqin Wu +8
The debris disk around ~Pictoris is known to contain gas. Previous ALMA observations revealed a CO belt at 85 au with a distinct clump, interpreted as a location of enhanc…
Location and sizes of forsterite grains in protoplanetary disks: interpretation from the Herschel DIGIT programme
K. M. Maaskant, B. L. de Vries, M. Min +4
The spectra of protoplanetary disks contain mid- and far- infrared emission features produced by forsterite dust grains. The spectral features contain information about the forster…
Herschel/PACS observations of the 69 band of crystalline olivine around evolved stars
J. A. D. L. Blommaert, B. L. de Vries, L. B. F. M. Waters +15
We present 48 Herschel/PACS spectra of evolved stars in the wavelength range of 67-72 m. This wavelength range covers the 69 m band of crystalline olivine ($\text{Mg}_{2-2x}\…
Pulsating red giant stars in eccentric binary systems discovered from Kepler space-based photometry
P. G. Beck, K. Hambleton, J. Vos +30
The unparalleled photometric data obtained by NASA's Kepler space telescope led to an improved understanding of red giant stars and binary stars. Seismology allows us to constrain…
The problematically short superwind of OH/IR stars - Probing the outflow with the 69 μm spectral band of forsterite
B. L. de Vries, J. A. D. L. Blommaert, L. B. F. M. Waters +4
Spectra of OH/IR stars show prominent spectral bands of crystalline olivine (MgFeSiO). To learn more about the timescale of the outflows of OH/IR stars, w…
Detection of a large sample of Gamma Dor stars from Kepler space photometry and high-resolution ground-based spectroscopy
A. Tkachenko, C. Aerts, A. Yakushechkin +10
The space-missions MOST, CoRoT, and Kepler deliver a huge amount of high-quality photometric data suitable to study numerous pulsating stars. Our ultimate goal is a detection and a…
Observational evidence for composite grains in an AGB outflow: MgS in the extreme carbon star LL Peg
R. Lombaert, B. L. de Vries, A. de Koter +5
The broad 30 μm feature in carbon stars is commonly attributed to MgS dust particles. However, reproducing the 30 μm feature with homogeneous MgS grains would require much more sul…
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…
