Do A-type stars flare?
M. G. Pedersen, V. Antoci, H. Korhonen +5
For flares to be generated, stars have to have a sufficiently deep outer convection zone (F5 and later), strong large--scale magnetic fields (Ap/Bp-type stars) or strong, radiative…
MiNDSTEp differential photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756: Microlensing and a new time delay
E. Giannini, R. W. Schmidt, J. Wambsganß +52
We present V and R photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756. The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope…
The Age and Distance of the Kepler Open Cluster NGC 6811 from an Eclipsing Binary, Turnoff Star Pulsation, and Giant Asteroseismology
Eric L. Sandquist, J. Jessen-Hansen, Matthew D. Shetrone +9
We present the analysis of an eccentric, partially eclipsing long-period ( d) binary system KIC 9777062 that contains main sequence stars near the turnoff of the intermedi…
Detection of solar-like oscillations in relics of the Milky Way: asteroseismology of K giants in M4 using data from the NASA K2 mission
A. Miglio, W. J. Chaplin, K. Brogaard +18
Asteroseismic constraints on K giants make it possible to infer radii, masses and ages of tens of thousands of field stars. Tests against independent estimates of these properties…
The K2-ESPRINT Project V: a short-period giant planet orbiting a subgiant star
Vincent Van Eylen, Simon Albrecht, Davide Gandolfi +31
We report on the discovery and characterization of the transiting planet K2-39b (EPIC 206247743b). With an orbital period of 4.6 days, it is the shortest-period planet orbiting a s…
Testing Asteroseismic Scaling Relations using Eclipsing Binaries in Star Clusters and the Field
K. Brogaard, J. Jessen-Hansen, R. Handberg +10
The accuracy of stellar masses and radii determined from asteroseismology is not known! We examine this issue for giant stars by comparing classical measurements of detached eclips…
