Stellar modelling of Spica, a high-mass spectroscopic binary with a beta Cep variable primary component
A. Tkachenko, J. M. Matthews, C. Aerts +16
Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with high accuracy and in a model-in…
MOST light-curve analysis of the gamma Dor pulsator HR 8799, showing resonances and amplitude variations
Á. Sódor, A. -N. Chené, P. De Cat +13
Context: The central star of the HR 8799 system is a gamma Doradus-type pulsator. The system harbours four planetary-mass companions detected by direct imaging, and is a good solar…
The Mass of the Planet-hosting Giant Star Beta Geminorum Determined from its p-mode Oscillation Spectrum
A. P. Hatzes, M. Zechmeister, J. Matthews +7
We use precise radial velocity measurements and photometric data to derive the frequency spacing of the p-mode oscillation spectrum of the planet-hosting star Beta Gem. This spacin…
Proper Motions and Internal Dynamics in the Core of the Globular Cluster M71
Raminder Singh Samra, Harvey B. Richer, Jeremy S. Heyl +4
We have used Gemini North together with the NIRI-ALTAIR adaptive optics imager in the H and K bands to explore the core of the Galactic globular cluster M71 (NGC 6838). We obtained…
Identification of HCCC as a diffuse interstellar band carrier
J. P. Maier, G. A. H. Walker, D. A. Bohlender +5
We present strong evidence that the broad, diffuse interstellar bands (DIBs) at 4881 and 5450\,Åare caused by the B\,\,A transition of HCCC (l…
A coincidence between a hydrocarbon plasma absorption spectrum and the lambda 5450 DIB
H. Linnartz, N. Wehres, H. Van Winckel +5
The aim of this work is to link the broad lambda 5450 diffuse interstellar band (DIB) to a laboratory spectrum recorded through an expanding acetylene plasma. Cavity ring-down dire…
