A case study of ACV variables discovered in the Zwicky Transient Facility survey
N. Faltová, K. Kallová, M. Prišegen +6
Magnetic chemically peculiar (mCP) stars exhibit complex atmospheres that allow the investigation of the interplay of atomic diffusion, magnetic fields, and stellar rotation. A non…
High-Amplitude gamma Doradus Variables
Ernst Paunzen, Klaus Bernhard, Stefan Huemmerich +3
According to most literature sources, the amplitude of the pulsational variability observed in gamma Doradus stars does not exceed 0.1 mag in Johnson V. We have analyzed fifteen hi…
Rotational modulation and single g-mode pulsation in the B9pSi star HD174356?
Z. Mikulasek, E. Paunzen, S. Huemmerich +19
Chemically peculiar (CP) stars of the upper main sequence are characterised by specific anomalies in the photospheric abundances of some chemical elements. The group of CP2 stars,…
A plethora of new, magnetic chemically peculiar stars from LAMOST DR4
Stefan Huemmerich, Ernst Paunzen, Klaus Bernhard
Magnetic chemically peculiar (mCP) stars are important to astrophysics because their complex atmospheres lend themselves perfectly to the investigation of the interplay between suc…
New and improved rotational periods of magnetic CP stars from ASAS-3, KELT and MASCARA data
Klaus Bernhard, Stefan Huemmerich, Ernst Paunzen
Magnetic chemically peculiar (mCP) stars allow the investigation of such diverse phenomena as atomic diffusion, magnetic fields and stellar rotation. The aim of the present investi…
TYC 3637-1152-1 - a High Amplitude delta Scuti star with peculiar pulsational properties
Ernst Paunzen, Klaus Bernhard, Moriz Frauenberger +16
In some delta Scuti stars, only one or two radial modes are excited (usually the fundamental mode and/or first overtone mode) and the observed peak-to-peak amplitudes exceed 0.3 ma…
Orbital parameters and evolutionary status of the highly peculiar binary system HD 66051
E. Paunzen, M. Fedurco, K. G. Helminiak +8
The spectroscopic binary system HD 66051 (V414 Pup) consists of a highly peculiar CP3 (HgMn) star and an A-type component. It also shows out-of-eclipse variability that is due to c…
An investigation of the RCB star candidate GDS J0702414-023501
Stefan Huemmerich, Klaus Bernhard
2MASS J07024146-0235017 = GDS J0702414-023501 was included in the "Catalogue enriched with R CrB stars" on grounds of its near- and mid-infrared colours. The object, which correspo…
1SWASP J022916.91-395901.4 - a Possible New VY Sculptoris Variable in Eridanus
Stefan Huemmerich, Klaus Bernhard, Gregor Srdoc
We report the discovery of 1SWASP J022916.91-395901.4 = GSC 07552-00389, a possible new VY Sculptoris variable in Eridanus, which is associated with the X-ray source 1RXS J022917.1…
New R Coronae Borealis and DY Persei Star Candidates and Other Related Objects Found in Photometric Surveys
Sebastián Otero, Stefan Huemmerich, Klaus Bernhard +1
We have carried out a search for new R Coronae Borealis (RCB) variables using the publicly accessible data from various photometric sky surveys and-whenever available-AAVSO visual…
New Mira Variables from the MACHO Galactic Bulge Fields, part II
Klaus Bernhard, Stefan Huemmerich
We present a new sample of 525 Mira variables in the direction of the Galactic Bulge, expanding on previous samples of 69 and 500 objects, respectively, and thereby concluding our…
