Unveiling the period-bounce population of cataclysmic variables: Spectroscopic and time-domain follow-up of eROSITA-selected candidates
S. Hernández-DÃaz, B. Stelzer, A. Schwope +9
The paper presents spectroscopic and time‑domain follow‑up of eROSITA‑selected cataclysmic variable candidates, confirming 24 new systems and showing they are consistent with perio…
The Volans-Carina association An X-ray Bridge Between Younger and Older Stellar Populations
Daniela Muñoz-Giraldo, Beate Stelzer, Alex Binks +3
The paper refines the membership of the Volans‑Carina association using Gaia DR3 data and provides a nearly complete X‑ray census, showing its stars have coronal activity comparabl…
Balmer decrements as a new diagnostic for period-bounce Cataclysmic Variable stars
Santiago Hernández-DÃaz, Beate Stelzer, Daniela Muñoz-Giraldo
Cataclysmic variable stars (CVs) evolve toward shorter orbital periods () until they reach a minimum near min. Beyond this point, the…
A systematic search for orbital periods of polars with TESS. Methods, detection limits, and results
Santiago Hernández-DÃaz, Beate Stelzer, Axel Schwope +1
Context. Determining the orbital periods of cataclysmic variable stars (CVs) is essential for confirming candidates and for the understanding of their evolutionary state. The Trans…
eROSITA-selection of new period-bounce Cataclysmic Variables: First follow-up confirmation using TESS and SDSS
Daniela Muñoz-Giraldo, Beate Stelzer, Axel Schwope +3
Between 40 and 80 of cataclysmic variables (CVs) are expected to have evolved past the period-minimum and contain a degenerate donor. However, observational surveys for CVs…
