# High-speed photometry of faint cataclysmic variables - IX. Targets from multiple transient surveys

## TL;DR

This study provides high-speed photometric data for 25 faint cataclysmic variables from multiple transient surveys, revealing new orbital and superhump periods, outburst cycles, and system classifications.

## Contribution

It reports 16 new orbital periods, one superhump period, and characterizes various types of cataclysmic variables from survey data, expanding the understanding of these systems.

## Key findings

- 16 new orbital periods identified
- 1 new superhump period discovered
- Characterization of outburst cycles and system types

## Abstract

We present high-speed photometric observations of 25 cataclysmic variables detected by the All Sky Automated Search for Super-Novae (ASAS-SN), the Mobile Astronomical System of the TElescope-Robot (MASTER) and the Catalina Real-Time Transient Survey (CRTS). From these observations we determine 16 new orbital periods and 1 new superhump period. Two systems (ASASSN-14ik and ASASSN-14ka) have outburst periods of approximately 1 month, with a third (ASASSN-14hv) having outbursts approximately every 2 months. Included in the sample are 11 eclipsing systems, one probable intermediate polar (ASASSN-15fm), 1 SW Sex-type star (MLS 0720+17), 1 WZ Sge-type star (ASASSN-17fz) and one system showing different photometric and spectroscopic periods (ASASSN-15kw).
