Constrained fitting of disentangled binary spectra: application to V615 Per in the open cluster h Persei
E. Tamajo, K. Pavlovski, J. Southworth
Using the technique of spectral disentangling, it is possible to determine the individual spectra of the components of a multiple star system from composite spectra observed at a r…
Regularities in frequency spacings of Delta Scuti stars: The Kepler star KIC 9700322
M. Breger, L. Balona, P. Lenz +15
In the faint star KIC 9700322 observed by the Kepler satellite, 76 frequencies with amplitudes from 14 to 29000 ppm were detected. The two dominant frequencies at 9.79 and 12.57 c/…
The Hyper-MUCHFUSS project: probing the Galactic halo with sdB stars
A. Tillich, U. Heber, S. Geier +7
High-velocity stars in the Galactic halo, e.g. the so-called hyper-velocity stars (HVS), are important tracers of the properties of the dark matter halo, in particular its mass. Ba…
Massive unseen companions to hot faint underluminous stars from SDSS (MUCHFUSS) - Analysis of seven close subdwarf B binaries
S. Geier, P. F. L. Maxted, R. Napiwotzki +12
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions like massive white dw…
Ice chemistry in massive Young Stellar Objects: the role of metallicity
J. M. Oliveira, J. Th. van Loon, G. C. Sloan +6
We present the comparison of the three most important ice constituents (water, CO and CO2) in the envelopes of massive Young Stellar Objects (YSOs), in environments of different me…
Identification of the Lithium Depletion Boundary and Age of the Southern Open Cluster Blanco 1
P. A. Cargile, D. J. James, R. D. Jeffries
We present results from a spectroscopic study of the very low mass members of the Southern open cluster Blanco 1 using the Gemini-N telescope. We obtained intermediate resolution (…
