Abstract:
Continuing the project described by Kato et al. (2009PASJ...61S.395K 2009PASJ...61S.395K),
we collected times of superhump maxima for 127 SU UMa-type dwarf novae
observed mainly during the 2016-2017 season and characterized these
objects. We provide updated statistics of the relation between the
orbital period and the variation of superhumps, the relation between
period variations and the rebrightening type in WZ Sge-type objects.
We obtained the period minimum of 0.05290(2)d and confirmed the
presence of the period gap above the orbital period ∼0.09d. We
note that four objects (NY Her, 1RXS J161659.5+620014,
CRTS J033349.8-282244, and SDSS J153015.04+094946.3) have
supercycles shorter than 100d but show infrequent normal outbursts. We
consider that these objects are similar to V503 Cyg, whose normal
outbursts are likely suppressed by a disk tilt. These four objects are
excellent candidates to search for negative superhumps. DDE 48 appears
to be a member of ER UMa-type dwarf novae. We identified a new
eclipsing SU UMa-type object, MASTER OT J220559.40-341434.9. We
observed 21 WZ Sge-type dwarf novae during this interval and report 18
of them in this paper. Among them, ASASSN-16js is a good candidate for
a period bouncer. ASASSN-16ia showed a precursor outburst for the
first time in a WZ Sge-type superoutburst. ASASSN-16kg, CRTS
J000130.5+050624, and SDSS J113551.09+532246.2 are located in the
period gap. We have newly obtained 15 orbital periods, including
periods from early superhumps.
Description:
The data were obtained under campaigns led by the Variable Star
Network (VSNET) Collaboration (Kato et al., 2004PASJ...56S...1K 2004PASJ...56S...1K). We
also used the public data from the American Association of Variable
Star Observers (AAVSO) International Database
(https://www.aavso.org/data-download). Outburst detections of many new
and known objects relied on the All-Sky Automated Survey for
Supernovae (ASAS-SN) CV patrol (Davis et al. 2015,
http://cv.asassn.astronomy.ohio-state.edu/) the MASTER network
(Gorbovskoy et al., 2013ARep...57..233G 2013ARep...57..233G), and the Catalina Real-time
Transient Survey (CRTS: Drake et al. 2009,
http://nesssi.cacr.caltech.edu/catalina/) in addition to outburst
detections reported to VSNET, AAVSO (https://www.aavso.org), British
Astronomical Association, Variable Star Section (BAAVSS) alert
(https://groups.yahoo.com/neo/groups/baavss-alert), and cvnet-outburst
(https://groups.yahoo.com/neo/groups/cvnet-outburst).
