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 in 2023.
This is the seventh 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 will be 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.
The workshop participation is by invitation only.
All participants are kindly invited to attend the whole workshop.
The workshop will include several 30-min talks to introduce the
current problems, and typically 20-min talks giving new experimental
and theoretical results. A series of 15-min talks will be devoted
to ongoing and next generation experiments.
In order to keep alive the workshop it was decided that all presentations should be
compulsorily given to the LOC, so that they can be inserted into the web page of the workshop.
These presentations will form the basis for writing the papers to be submitted for publication in PoS-SISSA.
The submitted papers will follow a peer referee process. The proceedings will be available soon also in NASA-ADS.
The editor of the proceedings will be Franco Giovannelli.
