Photometric study of hot Algol-type binaries with long cycles
J. Garcés, R. E. Mennickent, J. Petrovíc +6
Double periodic variables (DPVs) are hot Algol-type interacting binary systems with an orbital and a long photometric cycle. The origin of the latter may be related to cyclic struc…
The vanishing of the long photometric cycle in AU Monocerotis
L. Celedón, R. E. Mennickent, D. Barría +2
Double periodic variables (DPVs) are a group of semi-detached interacting binaries that exhibit a long photometric cycle with an average length of times the orbital period…
Non-thermal radio emission in Sakurai's Object
Marcin Hajduk, Peter A. M. van Hoof, Albert A. Zijlstra +5
The very late thermal pulse (VLTP) affects the evolution of 20\% of 1--8\, stars, repeating the last phases of the red giant within a few years and leading t…
Stellar Astrophysics and Exoplanet Science with the Maunakea Spectroscopic Explorer (MSE)
Maria Bergemann, Daniel Huber, Vardan Adibekyan +70
The Maunakea Spectroscopic Explorer (MSE) is a planned 11.25-m aperture facility with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. A…
The planetary nebula IC 5148 and its ionized halo
D. Barría, S. Kimeswenger, W. Kausch +1
Many round or nearly roundish Planetary Nebulae (PNe) show multiple shells and halo structures during their evolutionary stage near the maximum temperature of their central star. C…
Planetary Nebulae distances in GAIA DR2
Stefan Kimeswenger, Daniela Barría
Context: Planetary Nebula distance scales often suffer for model dependent solutions. Model independent trigonometric parallaxes have been rare. Space based trigonometric parallaxe…
On the eclipsing binary ELHC 10 with occulting dark disc in the Large Magellanic Cloud
H. E. Garrido, R. E. Mennickent, G. Djurasevic +4
We investigate the luminous star ELHC 10 located in the bar of the Large Magellanic Cloud, concluding that it is a SB1 long-period eclipsing binary where the main eclipse is produc…
Exploring the long-term variability and evolutionary stage of the interacting binary DQ Velorum
D. Barría, R. E. Mennickent, D. Graczyk +1
To progress in the comprehension of the double periodic variable (DPV) phenomenon, we analyse a series of optical spectra of the DPV system DQ Velorum during much of its long-term…
Fundamental stellar and accretion disc parameters of the eclipsing binary DQ Velorum
D. Barría, R. E. Mennickent, L. Schmidtobreick +5
To add to the growing collection of well-studied double periodic variables (DPVs) we have carried out the first spectroscopic and photometric analysis of the eclipsing binary DQ Ve…
