Evolution of the disk of pi Aqr: from near-disappearance to a strong maximum
Y. Naze, G. Rauw, J . Guarro Flo +30
Some Be stars display important variability of the strength of the emission lines formed in their disk. This is notably the case of pi Aqr. We present here the recent evolution of…
Dynamical structure of the pulsating atmosphere of RR Lyr - I. A typical pulsation cycle
D. Gillet, B. Mauclaire, T. Lemoult +5
RRab stars are large amplitude pulsating stars in which the pulsation is associated with strong shock wake propagating in the atmosphere. The objective of this study is to provide…
First observation of H redshifted emission in RR Lyr
D. Gillet, B. Mauclaire, T. Garrel +10
The so-called H third emission occurs around pulsation phase =0.30. It has been observed for the first time in 2011 in some RR Lyrae stars. The emission intensity is very wea…
New outburst of the symbiotic nova AG Peg after 165 years
A. Skopal, S. Yu. Shugarov, M. Sekeráš +13
AG Peg is known as the slowest symbiotic nova, which experienced its nova-like outburst around 1850. After 165 years, during June of 2015, it erupted again showing characteristics…
Reaching sub-milimag photometric precision on Beta Pictoris with a nanosat: the PicSat mission
M. Nowak, S. Lacour, V. Lapeyrère +6
PicSat is a nanosatellite currently being developed to observe the transit of the giant planet \b{eta} Pictoris, expected some time between July 2017 and June 2018. The mission is…
A Coordinated X-ray and Optical Campaign of the Nearest Massive Eclipsing Binary, delta Orionis Aa: III. Analysis of Optical Photometric MOST and Spectroscopic (Ground Based) Variations
Herbert Pablo, Noel D. Richardson, Anthony F. J. Moffat +44
We report on both high-precision photometry from the MOST space telescope and ground-based spectroscopy of the triple system delta Ori A consisting of a binary O9.5II+early-B (Aa1…
