A Phenomenon Resembling Early Superhumps in a New SU UMa-type Dwarf Nova with a 2 hr Orbital Period
The Astronomical JournalWe investigate K2BS5, an optical transient that we identified in Campaign 13 of the Kepler/K2 archives by the K2 Background Survey, and classify it as a new SU UMa-type dwarf nova.

Searching for nova shells around cataclysmic variables [PDF]
, 2015 We present the results of a search for nova shells around 101 cataclysmic variables (CVs), using Halpha images taken with the 4.2-m William Herschel Telescope (WHT) and the 2.5-m Isaac Newton Telescope Photometric Halpha Survey of the Northern Galactic ...

The Astrophysical JournalRecurrent nova U Scorpii (U Sco) is one of the prototypes for a Type Ia supernova progenitor. The logic is that the white dwarf is near the Chandrasekhar mass and gas is accumulating onto its surface at a near-maximal accretion rate, so it will soon ...

MULTI-FREQUENCY STUDY OF SYMBIOTIC NOVAE
Odessa Astronomical Publications, 2017 Symbiotic novae are subclass of symbiotic stars - interacting binaries with wide orbits, whose photometric history is characterized by a single nova- like outburst lasting decades and caused by a thermonuclear runaway on the surface of a wind accreting ...

Pan-chromatic observations of the remarkable nova LMC 2012
, 2014 We present the results of an intensive multiwavelength campaign on nova LMC 2012. This nova evolved very rapidly in all observed wavelengths. The time to fall two magnitudes in the V band was only 2 days.

On the change of the inner boundary of an optically thick accretion disk around white dwarfs using the dwarf nova SS Cyg as an example [PDF]
, 2012 We present the results of our studies of the aperiodic optical flux variability for SS Cyg, an accreting binary systemwith a white dwarf. The main set of observational data presented here was obtained with the ANDOR/iXon DU-888 photometer mounted on the ...

Human Brain Mapping, Volume 46, Issue 18, 15 December 2025.We leveraged in vivo 7T GluCEST MRI and normative PET receptor maps to examine the spatial covariation between cortical glutamate levels and receptor expression. GluCEST signal showed positive spatial associations with NMDA and GABAA, but not mGluR5. These findings enhance our understanding of GluCEST and glutamate‐receptor dynamics across the cortex ...

, 2003 We photometrically observed four southern dwarf novae in outburst (NSV 10934, MM Sco, AB Nor and CAL 86). NSV 10934 was confirmed to be an SU UMa-type dwarf nova with a mean superhump period of 0.07478(1) d.
