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…
The enigmatic nature of the circumstellar envelope and bow shock surrounding Betelgeuse as revealed by Herschel. I. Evidence of clumps, multiple arcs, and a linear bar-like structure
L. Decin, N. L. J. Cox, P. Royer +13
Context. The interaction between stellar winds and the interstellar medium (ISM) can create complex bow shocks. The photometers on board the Herschel Space Observatory are ideally…
An independent distance estimate to CW Leo
M. A. T. Groenewegen, M. J. Barlow, J. A. D. L. Blommaert +13
CW Leo has been observed six times between October 2009 and June 2012 with the SPIRE instrument on board the Herschel satellite. Variability has been detected in the flux emitted b…
The Invisible Monster Has Two Faces: Observations of Epsilon Aurigae with the Herschel Space Observatory
D. W. Hoard, D. Ladjal, R. E. Stencel +1
We present Herschel Space Observatory photometric observations of the unique, long-period eclipsing binary star Epsilon Aurigae. Its extended spectral energy distribution is consis…
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 far-infrared survey of bow shocks and detached shells around AGB stars and red supergiants
N. L. J. Cox, F. Kerschbaum, A. -J. van Marle +16
Far-infrared Herschel/PACS images at 70 and 160 micron of a sample of 78 Galactic evolved stars are used to study the (dust) emission structures, originating from stellar wind-ISM…
MESS (Mass-loss of Evolved StarS), a Herschel Key Program
M. A. T. Groenewegen, C. Waelkens, M. J. Barlow +39
MESS (Mass-loss of Evolved StarS) is a Guaranteed Time Key Program that uses the PACS and SPIRE instruments on board the Herschel Space Observatory to observe a representative samp…
870 um observations of evolved stars with LABOCA
D. Ladjal, K. Justtanont, M. A. T. Groenewegen +3
During their evolution, Asymptotic Giant Branch (AGB) stars experience a high mass-loss which leads to the formation of a Circumstellar Envelope (CSE) of dust and gas. The mass-los…
Photometric multi-site campaign on the open cluster NGC 884 I. Detection of the variable stars
S. Saesen, F. Carrier, A. Pigulski +62
CONTEXT: Recent progress in the seismic interpretation of field beta Cep stars has resulted in improvements of the physics in the stellar structure and evolution models of massive…
HD 174884: a strongly eccentric, short-period early-type binary system discovered by CoRoT
C. Maceroni, J. Montalban, E. Michel +12
Accurate photometric CoRoT space observations of a secondary seismological target, HD 174884, led to the discovery that this star is an astrophysically important double-lined eclip…
Post-AGB stars with hot circumstellar dust: binarity of the low-amplitude pulsators
Hans Van Winckel, Tom Lloyd Evans, Maryline Briquet +28
While the first binary post-AGB stars were serendipitously discovered, the distinct characteristics of their Spectral Energy Distribution (SED) allowed us to launch a more systemat…
Near-IR spectroscopic ages of massive star clusters in M82
A. Lançon, J. S. Gallagher, M. Mouhcine +3
Like other starburst galaxies, M82 hosts compact, massive young star clusters that are interesting both in their own right and as benchmarks for population synthesis models. Can sp…
Near-IR Spectra of Red Supergiants and Giants. I- Models with Solar and with Mixing-Induced Surface Abundance Ratios
A. Lançon, P. H. Hauschildt, D. Ladjal +1
We provide a grid of PHOENIX spectra of red giant and supergiant stars, that extend through optical and near-IR wavelengths. For the first time, models are also provided with modif…
Modelling the Near-IR Spectra of Red Supergiant-dominated Populations
A. Lançon, J. S. Gallagher, R. de Grijs +6
We report on recent progress in the modelling of the near-IR spectra of young stellar populations, i.e. populations in which red supergiants (RSGs) are dominant. First, we discuss…
