Abstract:
We present an overview and catalogue of all known mass-transferring
binary systems that have white dwarf accretors and orbital periods
shorter than 70 minutes, including the AM CVn-type binary systems and
a number of related objects. In this paper, we provide an overview of
the literature background and describe recent breakthroughs, open
questions, and connections to other fields. This overview is intended
to provide a starting point for researchers who are relatively new to
the fields of ultracompact binaries or AM CVn-type binaries. We define
the scope of the catalogue (the criteria for inclusion) and describe
its format and contents (what data have been included for each
target). We also summarise the observed properties of the known
mass-transferring ultracompact binaries, including their orbital
periods and component stellar masses and radii. The catalogue
presented here aims to provide a central resource to enable
researchers to track the current status of the known sample. At the
time of writing, the catalogue includes 123 confirmed binaries and 29
candidates. The catalogue is hosted on a public platform (Zenodo) with
version control, and will be updated regularly.
