Dwarf nova-type cataclysmic variable stars are significant radio emitters by Coppejans, D., Kording, E., Miller-Jones, James, Rupen, M., Sivakoff, G., Knigge, C., Groot, P., Woudt, P., Waagen, E., Templeton, M.

“…We present 8–12 GHz radio light curves of five dwarf nova (DN) type cataclysmic variable stars (CVs) in outburst (RX And, U Gem, and Z Cam), or superoutburst (SU UMa and YZ Cnc), increasing the number of radio-detected DN by a factor of 2. …”

The massive eclipsing system ALS 1135 and variable stars in the field of the distant OB association Bochum 7 by Michalska, G., Niemczura, E., Pigulski, A., Steslicki, M., Williams, Andrew

“…The result shows thatthis method represents a viable alternative to isochrone fitting.A photometric search of the field of ALS 1135 resulted in the discovery of 17 variable stars,including 7 pulsating ones. One of them is a slowly-pulsating B (SPB) star belonging to VelOB1, the other six are d Scuti stars. …”
