The eta Aquilae System: Radial Velocities and Astrometry in Search of eta Aql B
G. Fritz Benedict, Thomas G. Barnes, Nancy R. Evans +4
The classical Cepheid eta Aql was not included in past Leavitt Law work (Benedict et al. 2007) because of a presumed complicating orbit due to a known B9.8V companion. To determine…
Pulsational instability of pre-main sequence models from accreting protostars. I. Constraining the input physics for accretion with spectroscopic parameters and stellar pulsations
T. Steindl, K. Zwintz, T. G. Barnes +2
Context: The pre-main sequence evolution is often simplified by choosing classical initial models. These have large initial radii and sufficient uniform contraction to make them fu…
A comprehensive study of young B stars in NGC 2264: I. Space photometry and asteroseismology
K. Zwintz, E. Moravveji, P. I. Papics +9
Space photometric time series of the most massive members of the young open cluster NGC 2264 allow us to study their different sources of variability down to the millimagnitude lev…
New systemic radial velocities of suspected RR Lyrae binary stars
Elisabeth Guggenberger, Thomas G. Barnes, Katrien Kolenberg
Among the tens of thousands of known RR Lyrae stars there are only a handful that show indications of possible binarity. The question why this is the case is still unsolved, and ha…
Echography of young stars reveals their evolution
K. Zwintz, L. Fossati, T. Ryabchikova +17
We demonstrate that a seismic analysis of stars in their earliest evolutionary phases is a powerful method to identify young stars and distinguish their evolutionary states. The ea…
Two spotted and magnetic early B-type stars in the young open cluster NGC2264 discovered by MOST and ESPaDOnS
L. Fossati, K. Zwintz, N. Castro +9
Star clusters are known as superb tools for understanding stellar evolution. In a quest for understanding the physical origin of magnetism and chemical peculiarity in about 7% of t…
