Reconsidering The Bailey Diagrams of ab-type RR Lyrae Stars, Metallicity-Mediated Evolution as the Direct Cause of the Oosterhoff Phenomenon

L. -J. Li, S. -B. Qian, L. -Y. Zhu +2

We re-examine the Bailey diagrams of fundamental mode RR Lyrae stars from the perspective of horizontal branch (HB) evolution, identifying evolutionary effects as the probable dire…

Two Different Weak Modulations in ab-type RR Lyrae Variable V838 Cyg, and Potential Influence of Metal Abundance on Blazhko Modulation

L. -J. Li, S. -B. Qian, X. -D. Shi +1

Noting the weakest modulation and relatively high metal abundance of the ab-type RR Lyrae star V838 Cyg, we collected the photometric data of this star from several sky surveys to…

Reanalysis of c-type RR Lyrae Variable BE Dor, Period Modulations and Possible Mechanism

L. -J. Li, S. -B. Qian, L. -Y. Zhu

We reanalyzed the c-type RR Lyrae star BE Dor (MACHO 5.4644.8, OGLE-LMC-RRLYR-06002) that had been discovered to show cyclic period changes. The photometric data of several sky sur…

Optical flares and flaring oscillations on the M-type eclipsing binary CU Cnc

Qian S. -B., J. Zhang, L. -Y. Zhu +7

We report here the discovery of an optical flare observed in R band from the red-dwarf eclipsing binary CU Cnc whose component stars are at the upper boundary of full convection (M…

Detection of a planetary system orbiting the eclipsing polar HU Aqr

S. -B. Qian, L. Liu, W. -P. Liao +7

Using the precise times of mid-egress of the eclipsing polar HU Aqr, we discovered that this polar is orbited by two or more giant planets. The two planets detected so far have mas…
