V838 Mon: A slow waking up of Sleeping Beauty?

T. Liimets, I. Kolka, M. Kraus +15

Context. V838 Monocerotis is a peculiar binary that underwent an immense stellar explosion in 2002, leaving behind an expanding cool supergiant and a hot B3V companion. Five years…

Spectroscopic confirmation of the binary nature of the hybrid pulsator KIC 5709664 found with the frequency modulation method

A. Derekas, S. J. Murphy, G. Dalya +14

We started a program to search for companions around hybrid Sct/ Dor stars with the frequency modulation method using Kepler data. Our best candidate was KIC 5709664, where…

Establishing the accuracy of asteroseismic mass and radius estimates of giant stars. I. Three eclipsing systems at [Fe/H]~ -0.3 and the need for a large high-precision sample

K. Brogaard, C. J. Hansen, A. Miglio +12

We aim to establish and improve the accuracy level of asteroseismic estimates of mass, radius, and age of giant stars. This can be achieved by measuring independent, accurate, and…

The [Y/Mg] clock works for evolved solar metallicity stars

D. Slumstrup, F. Grundahl, K. Brogaard +5

Previously [Y/Mg] has been proven to be an age indicator for solar twins. Here, we investigate if this relation also holds for helium-core-burning stars of solar metallicity. High…

An investigation of the formation and line properties of MgH in 3D hydrodynamical model stellar atmospheres

Anders O. Thygesen, Evan N. Kirby, Andrew J. Gallagher +4

Studies of the isotopic composition of magnesium in cool stars have so far relied upon the use of one-dimensional (1D) model atmospheres. Since the isotopic ratios derived are base…

Triangulum II: Not Especially Dense After All

Evan N. Kirby, Judith G. Cohen, Joshua D. Simon +3

Among the Milky Way satellites discovered in the past three years, Triangulum II has presented the most difficulty in revealing its dynamical status. Kirby et al. (2015a) identifie…
