A Survey of Novae in M83

A. W. Shafter, K. Hornoch, J. Benáček +14

The results of the first synoptic survey of novae in the barred spiral and starburst galaxy, M83 (NGC 5236), are presented. A total of 19 novae and one background supernova were di…

Improved model of the triple system V746 Cas that has a bipolar magnetic field associated with the tertiary

P. Harmanec, M. Brož, P. Mayer +9

V746 Cas is known to be a triple system composed of a close binary with an alternatively reported period of either 25.4d or 27.8d and a third component in a 62000d orbit. The objec…

Physical properties of seven binary and higher-order multiple OB systems

Pavel Mayer, Petr Harmanec, Rolf Chini +7

Analyses of multi-epoch, high-resolution (~ 50000) optical spectra of seven early-type systems provided various important new insights with respect to their multiplicity. First det…

A new look into the spectral and light variations of epsilon Aur

P. Harmanec, H. Božić, D. Korčáková +9

Investigating long series of spectral and photometric observations, we found that the orbital elements of epsilon Aur are subject to much larger uncertainties than usually believed…

Calcium Emission in Interacting Binary Be Stars

Pavel Koubský, Lenka Kotková, Viktor Votruba +7

Polidan (1976) suggested that Be stars showing the CaII IR triplet in emission are interacting binaries. With the advent of the Gaia satellite, which will host a spectrometer to ob…

The field high-amplitude SX Phe variable BL Cam: results from a multisite photometric campaign. II. Evidence of a binary - possibly triple - system

S. Fauvaud, J. -P. Sareyan, I. Ribas +45

Short-period high-amplitude pulsating stars of Population I ( Sct stars) and II (SX Phe variables) exist in the lower part of the classical (Cepheid) instability strip. Most of…

Properties and nature of Be stars: 27. Orbital and recent long-term variations of the Pleiades Be star Pleione = BU Tauri

J. Nemravová, P. Harmanec, J. Kubát +8

Radial-velocity variations of the H-alpha emission measured on the steep wings of the H-alpha line, prewhitened for the long-time changes, vary periodically with a period of (218.0…
