| contents | New Photometry and Spectroscopy of DW Cancri S. H. Ramírez O. Segura Montero R. Michel J. Echevarría Física, Astronomía y Matemáticas novae cataclysmic variables Binaries: spectroscopic techniques: photometric stars: individual: DW Cnc We present new observations of the cataclysmic variable DW Cancri, after the system recovered from a low state. We performed a power spectrum analysis that reveals a clear signal of the 38 min spin period in our photometric data. Our spectroscopic power spectrum search was consistent with studies performed before the low state, showing the orbital and spin modulations. Our Doppler Tomography study exhibits a disc structure and an enhanced asymmetric region, possibly related to a hot spot component. Furthermore, a wavelet transform analysis reveals the 70 min spin-orbit beat period. We interpret these results as an indication of a partial recovery of the system. However, DW Cnc does not yet show all the original photometric modulations reported before the low state. Thus, we propose further observations to elucidate if such original signals require more time to reactivate. 2022 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57175492004 https://www.redalyc.org/journal/571/57175492004/ https://www.redalyc.org/journal/571/57175492004/html/ https://www.redalyc.org/journal/571/57175492004/57175492004.epub https://www.redalyc.org/journal/571/57175492004/movil 10.22201/ia.01851101p.2022.58.01.04 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.58 |
