A long-term UBVRI photometric study of the pre-main sequence star V350 Cep

TL;DR

This study presents a decade-long UBVRI photometric analysis of V350 Cep, revealing its stable maximum brightness with minor variations, and suggesting it is an intermediate eruptive variable akin to V1647 Ori.

Contribution

It provides the first long-term optical photometric data of V350 Cep, characterizing its variability and proposing its classification as an intermediate eruptive star.

Findings

V350 Cep maintained maximum brightness with low amplitude variations.

The star is likely an intermediate between FUors and EXors.

V350 Cep's behavior is similar to V1647 Ori.

Abstract

Results from UBVRI optical photometric observations of the pre-main sequence star V350 Cep during the period 2004-2014 are presented. The star was discovered in 1977 due to its remarkable increase in brightness by more than 5 mag (R). In previous studies, V350 Cep was considered a to be a potential FUor or EXor eruptive variables. Our data suggest that during the period of observations the star maintains its maximum brightness with low amplitude photometric variations. Our conclusion is that V350 Cep was probably an intermediate object between FUors and EXors, similar to V1647 Ori.
