The Golden Age of Cataclysmic Variables and Related Objects - VI

GOLDEN2023 - (other golden conferences)
4-9 September 2023
Palermo - (Mondello), Italy

In 2011 we organized the first workshop about "The Golden Age of Cataclysmic Variables and Related Objects"
because we were under the impression that the time for a comprehensive view had arrived.
We were right and surprised, mainly by the ongoing vigorous research and future coming prospects.
Thus we reached the conclusion that the state of the field, namely high activity and many observational results, calls for organizing follow-up workshops in a series of "The Golden Age of Cataclysmic Variables and Related Objects".
After the long interruption of the Palermo Workshop series due to the Covid-19 Pandemic, we are finally able to restart this series in complete safety. This is the sixth edition of such series.
One of the main field drivers were the results from the INTEGRAL experiment: detections of hard X-ray emission from a large sample of CVs, mainly intermediate polars. Undoubtedly, non-magnetic CVs, intermediate polars and polars constitute the most powerful
probe to test our theories of the various modes of accretion. The long term evolution of CV systems accreting at a prohibitive rate has become a hot topic both in terms of the fate of such systems (all sorts of supernovae) and the microphysics of Eddington and super Eddington mass accretion and mass loss flows. In particular we stress one of the hottest topics in present day astrophysics, namely the
progenitors of SN-Ia. This problem is connected with fundamental issues in cosmology. Novae and recurrent novae are the most promising progenitor candidates but so far could not be nailed down.
Our goal is to discuss what is missing in our knowledge of CVs that will allow a unique determination and observational confirmation.
Indeed the sub-class of CVs, named Classical Novae, which are the third most powerful stellar explosions in a galaxy, have been observed as close as a kpc and as far as galaxies in the Fornax cluster. The time to report on the recent renaissance in CNe studies thanks to observations with 8-10m class telescopes, high resolution spectroscopy, in synergy with observations from space
carried out with Swift, XMM, Chandra, HST, and Spitzer, and JWST coupled with recent advances in the theory of the outburst, seems now in order. The purpose of this workshop is to bring together about *80 invited researchers* from world wide to discuss the experimental updated panorama and theories of CVs and Related Objects.

The following topics have been discussed:

Opening Remarks (the Importance of Multifrequency Observations)

Cataclysmic Variables (non-magnetic, intermediate polars, polars)

Fundamental parameters
Accretion physics
Outburst physics
Magnetic phenomena
Interconnection among classes
Long term secular evolution
The fate of CVs

Classical and Recurrent Novae
Nova-like Stars
Symbiotic stars
The Astrophysics of CVs and related Objects with the Ongoing and Future Space-Based and Ground-Based Experiments.
