Twenty-Two New Variable Stars in the Northern Sky and Light Elements Improvement for PT Lyr, [WM2007] 1157, and [WM2007] 1160

TL;DR

This paper reports the discovery of twenty-two new variable stars in the Northern Sky, classifies their types, and provides updated information on three known variables to improve their characterization.

Contribution

It introduces twenty-two newly identified variable stars and refines the data on three known variables, enhancing the understanding of their light elements.

Findings

22 new variable stars discovered in the Northern Sky

Updated ephemeris for PT Lyr, [WM2007] 1157, and [WM2007] 1160

Classification of new variables into eclipsing, pulsating, rotating, and unknown types

Abstract

I report the discovery of twenty-two new variable stars in the Northern Sky: eleven eclipsing, seven pulsating (one of which is suspected), three rotating, and one of unspecified type. Three already known variables (PT Lyr, [WM2007] 1157, and [WM2007] 1160) have been studied more carefully in order to clarify their characterization or provide updated ephemeris.
