33 Lib - analog of gamma Equ

TL;DR

This paper investigates the magnetic field variability of the Ap star 33 Lib, revealing a probable 83.5-year period and shorter possible periods, indicating it is a slow rotator similar to gamma Equ.

Contribution

It identifies and analyzes the magnetic variability periods of 33 Lib, contributing new observational data on its long-term magnetic behavior.

Findings

Probable magnetic period of 83.5 years

Possible shorter periods: 11.036, 7.649, 4.690 days

Star is a slow rotator comparable to gamma Equ

Abstract

In this paper we study periodic variability of the magnetic field in the Ap star 33 Lib. We found that its most probable period equals 83.5 years. There exist also possible shorter periods: 11.036 days, 7.649 days and 4.690 days. Analysis of the magnetic behavior of 33 Lib allows us to conclude, that the star shows the second longest period the slow rotator gamma Equ, the latter star with the period of 97 years.
