# Variable stars in the northern Galactic plane from KISOGP

## TL;DR

This large-scale survey of the northern Galactic plane using KISOGP identified thousands of variable stars, including many previously unreported, demonstrating the survey's effectiveness in discovering bright variables.

## Contribution

The paper presents a comprehensive survey of the northern Galactic plane with new variable star discoveries, especially Cepheids and Miras, using multi-epoch I-band observations over five years.

## Key findings

- Detected thousands of variable stars, including ~100 Cepheids and >700 Miras.
- Approximately 90% of these variables are newly reported.
- Survey demonstrates many bright variables remain undiscovered in the Galactic plane.

## Abstract

We have conducted a large-scale survey of the northern plane using Kiso Wide Field Camera attached to Schmidt telescope at Kiso observatory. The KISOGP (KWFC Intensive Survey of the Galactic Plane) project have made 40-70 epoch observations in I band of about 320 sq. degrees for 5 years starting in 2012. The limiting magnitude is around 16.5 in I. In the data analysis so far, we detected a couple of thousands of variable stars including approximately 100 Cepheids and more than 700 Miras. Roughly 90 percent of them were not previously reported as variable stars, indicating that there are still many relatively bright variables to be found in the Galactic plane.
