The Chandra Planetary Nebulae Survey (ChanPlaNS): III. X-ray Emission from the Central Stars of Planetary Nebulae
R. Montez, J. H. Kastner, B. Balick +25
We present X-ray spectral analysis of 20 point-like X-ray sources detected in Chandra Planetary Nebula Survey (ChanPlaNS) observations of 59 planetary nebulae (PNe) in the solar ne…
Photometric properties of carbon stars in the Small Magellanic Cloud
G. C. Sloan, E. Lagadec, K. E. Kraemer +4
The Optical Gravitational Lensing Experiment identified over 1,800 carbon-rich Mira and semi-regular variables in the Small Magellanic Cloud. Multi-epoch infrared photometry reveal…
ALMA sub-mm maser and dust distribution of VY Canis Majoris
A. M. S. Richards, C. M. V. Impellizzeri, E. M. Humphreys +25
Cool, evolved stars have copious, enriched winds. The structure of these winds and the way they are accelerated is not well known. We need to improve our understanding by studying…
A study of rotating globular clusters - the case of the old, metal-poor globular cluster NGC 4372
N. Kacharov, P. Bianchini, A. Koch +7
Aims: We present the first in-depth study of the kinematic properties and derive the structural parameters of NGC 4372 based on the fit of a Plummer profile and a rotating, physica…
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 evolving spectrum of the planetary nebula Hen 2-260
M. Hajduk, P. A. M. van Hoof, K. Gesicki +3
We analysed the planetary nebula Hen 2-260 using optical spectroscopy and photometry. We compared our observations with the data from literature to search for evolutionary changes.…
A new HCN maser in IRAS 15082-4808
C. L. Smith, A. A. Zijlstra, G. A. Fuller
We have identified a new vibrational HCN maser at 89.087 GHz in the asymptotic giant branch (AGB) star IRAS 15082-4808, a maser which is thought to trace the innermost region of an…
