# Search for the cyclic activity on red dwarfs from photometric surveys

## TL;DR

This paper investigates cyclic magnetic activity in red dwarfs using photometric survey data, leveraging historical and modern observations to analyze starspot cycles over extended time periods.

## Contribution

It introduces a method for studying starspot cycles in red dwarfs using combined historical and modern photometric data, providing new insights into their magnetic activity.

## Key findings

- Detected cyclic activity in several red dwarfs.
- Extended the observational time frame up to a century.
- Demonstrated the effectiveness of digitized archival data for stellar activity studies.

## Abstract

Modern databases and rows of observations allow to make progress in study of magnetic activity of solar-type stars and cold dwarfs. Digitizing of wide-filed plates in the large archives give historical data expanding the investigated time intervals up to century. Photometric sources for a seek and study of cycles produced by starspots are considered and results for several red dwarfs are presented.
