An Investigation of Four Chemically Peculiar Stars with Photometric Periods below 12 Hours
Stefan Hümmerich, Klaus Bernhard, Ernst Paunzen +3
We present an investigation of three chemically peculiar (CP) stars and one CP star candidate which exhibit photometric periods below 12 hours. New spectroscopic observations have…
The beta Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
S. Messina, M. Millward, A. Buccino +19
We intended to compile the most complete catalog of bona fide members and candidate members of the beta Pictoris association, and to measure their rotation periods and basic proper…
Return of the King: Time-Series Photometry of FO Aquarii's Initial Recovery from its Unprecedented 2016 Low State
Colin Littlefield, Peter Garnavich, Mark R. Kennedy +28
In 2016 May, the intermediate polar FO~Aqr was detected in a low state for the first time in its observational history. We report time-resolved photometry of the system during its…
The orbital ephemeris of the classical nova RR Pictoris: presence of a third body?
N. Vogt, M. R. Schreiber, F. -J. Hambsch +4
The ex-nova RR Pic presents a periodic hump in its light curve which is considered to refer to its orbital period. Analyzing all available epochs of these hump maxima in the litera…
NSV 1907 - A new eclipsing, nova-like cataclysmic variable
Stefan Hümmerich, Rainer Gröbel, Franz-Josef Hambsch +6
NSV 1907, formerly listed as an irregular variable in variability catalogues, was classified as an Algol-type eclipsing binary in the Catalina Surveys Periodic Variable Star Catalo…
A radio pulsing white dwarf binary star
T. R. Marsh, B. T. Gänsicke, S. Hümmerich +23
White dwarfs are compact stars, similar in size to Earth but ~200,000 times more massive. Isolated white dwarfs emit most of their power from ultraviolet to near-infrared wavelengt…
