Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spectral type. Despite the existence of large libraries and the increasing

Internal rotation of the red-giant star KIC 4448777 by means of asteroseismic inversion

Autor: Di Mauro, M . P., Ventura, R., Cardini, D., Stello, D., Christensen-Dalsgaard, J., Dziembowski, W. A., Paterno', L., Beck, P. G., Bloemen, S., Davies, G. R., De Smedt, K., Elsworth, Y., Garcia, R. A., Hekker, S., Mosser, B., Tkachenko, A.

In this paper we study the dynamics of the stellar interior of the early red-giant star KIC 4448777 by asteroseismic inversion of 14 splittings of the dipole mixed modes obtained from {\it Kepler} observations. In order to overcome the complexity of

KIC 10080943: An eccentric binary system containing two pressure- and gravity-mode hybrid pulsators

Autor: Schmid, V. S., Tkachenko, A., Aerts, C., Degroote, P., Bloemen, S., Murphy, S. J., Van Reeth, T., Papics, P. I., Bedding, T. R., Keen, M. A., Prsa, A., Menu, J., Debosscher, J., Hrudkova, M., De Smedt, K., Lombaert, R., Nemeth, P.

Gamma Doradus and delta Scuti pulsators cover the transition region between low mass and massive main-sequence stars, and as such, are critical for testing stellar models. When they reside in binary systems, we can combine two independent methods to

The WISE View of RV Tauri Stars

Autor: Gezer, I., Van Winckel, H., Bozkurt, Z., De Smedt, K., Kamath, D., Hillen, M., Manick, R.

We present a detailed study based on infrared photometry of all Galactic RV Tauri stars from the General Catalogue of Variable Stars (GCVS). RV Tauri stars are the brightest among the population II Cepheids. They are thought to evolve away from the a

Asteroseismic fingerprints of rotation and mixing in the slowly pulsating B8 V star KIC 7760680

Autor: Pápics, P. I., Tkachenko, A., Aerts, C., Van Reeth, T., De Smedt, K., Hillen, M., Oestensen, R., Moravveji, E.

We present the first detection of a rotationally affected series consisting of 36 consecutive high-order sectoral dipole gravity modes in a slowly pulsating B (SPB) star. The results are based on the analysis of four years of virtually uninterrupted
