Understanding the spectra of isolated Herbig stars in the frame of a passive disk model
C. Dominik, C. P. Dullemond, L. B. F. M. Waters +1
We discuss spectral energy distributions of a sample of Herbig Ae/Be stars in the context of a passive irradiated disk model. The data have been presented earlier by Meeus et al (2…
A photometric mode identification method, including an improved non-adiabatic treatment of the atmosphere
M. -A. Dupret, J. De Ridder, P. De Cat +4
We present an improved version of the method of photometric mode identification of Heynderickx et al. (1994). Our new version is based on the inclusion of precise non-adiabatic eig…
Nonadiabatic resonant dynamic tides and orbital evolution in close binaries
B. Willems, T. Van Hoolst, P. Smeyers
This investigation is devoted to the effects of nonadiabatic resonant dynamic tides generated in a uniformly rotating stellar component of a close binary. The companion is consider…
Searching for Line Profile Variability in HgMn Stars
S. Turcotte, C. Aerts, P. Knoglinger
Spectra of four non-magnetic chemically peculiar late B type stars (HgMn) stars are analysed to detect periodic spectral line variations (LPVs). A procedure developed to study LPVs…
Cerium: the lithium substitute in post-AGB stars
Maarten Reyniers, Hans Van Winckel, Emile Biemont +1
In this letter we present an alternative identification for the line detected in the spectra of s-process enriched low-mass post-AGB stars around 6708A and which was interpreted in…
The dust disk of HR4049
C. Dominik, C. P. Dullemond, J. Cami +1
We present the Spectral Energy Distribution of HR 4049 based on literature data and new continuum measurements at 850 micron. The SED shows variable absorption in the UV, and a lar…
Infrared stellar populations in the central parts of the Milky Way galaxy
Jacco Th. van Loon, G. F. Gilmore, A. Omont +7
Near- and mid-IR survey data from DENIS and ISOGAL are used to investigate the structure and formation history of the inner 10 degree (1.4 kpc) of the Milky Way galaxy. Synthetic b…
Detection of Solar-like Oscillations in the G7 Giant Star xi Hya
S. Frandsen, F. Carrier, C. Aerts +9
We report the firm discovery of solar-like oscillations in a giant star. We monitored the star xi Hya (G7III) continuously during one month with the CORALIE spectrograph attached t…
Carbon stars in the Local Group
M. A. T. Groenewegen
The current status of carbon stars in the Local Group and beyond, is discussed. Although many carbon stars and late M-stars have been identified in Local Group galaxies, a coherent…
The mineral composition and spatial distribution of the dust ejecta of NGC 6302
F. Kemper, F. J. Molster, C. Jaeger +1
We have analysed the full ISO spectrum of the planetary nebula NGC 6302 in order to derive the mineralogical composition of the dust in the nebula. We use an optically thin dust mo…
ISO-SWS calibration and the accurate modelling of cool-star atmospheres - IV. G9 to M2 stars
L. Decin, B. Vandenbussche, C. Waelkens +5
presented. The 2.38 -- 4.08 micron wavelength-range of band 1 of ISO-SWS (Short-Wavelength Spectrometers on board of the Infrared Space Observatory) in which many different molecul…
ISO-SWS calibration and the accurate modelling of cool-star atmospheres - III. A0 to G2 stars
L. Decin, B. Vandenbussche, C. Waelkens +4
Vega, Sirius, Beta Leo, Alpha Car and Alpha Cen A belong to a sample of twenty stellar sources used for the calibration of the detectors of the Short-Wavelength Spectrometer on boa…
ISO-SWS calibration and the accurate modelling of cool-star atmospheres - II. General results
L. Decin, B. Vandenbussche, C. Waelkens +5
The fine calibration of the ISO-SWS detectors (Infrared Space Observatory - Short Wavelength Spectrometer) has proven to be a delicate problem. We therefore present a detailed spec…
On the distance of Magellanic Clouds: first overtone Cepheids
G. Bono, M. A. T. Groenewegen, M. Marconi +1
We present a detailed comparison between predicted and empirical PL_{I,K} relations and Wesenheit function for Galactic and Magellanic Clouds (MCs) First Overtone (FO) Cepheids. We…
ESO Imaging Survey. The Stellar Catalogue in the Chandra Deep Field South
M. A. T. Groenewegen, L. Girardi, E. Hatziminaoglou +10
(abridged) Stellar catalogues in five passbands (UBVRI) over an area of approximately 0.3 deg^2, comprising about 1200 objects, and in seven passbands (UBVRIJK) over approximately…
The rich 6 to 9 um spectrum of interstellar PAHs
E. Peeters, S. Hony, C. Van Kerckhoven +4
Here, we present 6-9 um spectra of a sample of RNe, HII regions, YSOs, evolved stars and galaxies that show strong unidentified infrared bands, obtained with the ISO-SWS. The IR em…
The ERE of the "Red Rectangle" revisited
Hans Van Winckel, Martin Cohen, Ted R. Gull
We present in this paper high signal-to-noise long-slit optical spectra of the Extended Red Emission (ERE) in the "Red Rectangle" (RR) nebula. These spectra, obtained at different…
The carrier of the "30" micron emission feature in evolved stars. A simple model using magnesium sulfide
S. Hony, L. B. F. M. Waters, A. G. G. M. Tielens
We present 2-45 micron spectra of a large sample of carbon-rich evolved stars in order to study the ``30'' micron feature. We find the ``30'' micron feature in sources in a wide ra…
