The Real-Time Evolution of Sakurai's Star (V4334 Sgr) and other (V)LTP Objects

摘要

We report on the progress of our on-going campaign to monitor the evolution of the VLTP objects V4334 Sgr and V605 Aql, as well as the suspected (V)LTP object CK Vul. V4334 Sgr does not show signs of increased ionization compared to our previous observations in 2004 We obtained the first radio detection of V605 Aql, indicating a strong increase in radio flux since 1987 We also present the first radio detection of CK Vul and discuss the expansion of the material ejected during the 1670 event.
