We report extensive new photometry and spectroscopy of the highly variable young stellar
object PTF 10nvg (also known as IRAS 20496+ 4354 and V2492 Cyg), including optical and …

Aims. We present results from optical photometric and spectroscopic observations of the
eruptive pre-main sequence star V582 Aur. Variability of the star was reported a few years …

We present the overview and first results from the North-PHASE Legacy Survey, which
follows six young clusters for five years, using the 2 deg FoV of the JAST80 telescope from …

In this paper results from the optical photometric observations of the pre-main sequence star
V1180 Cas are reported. The star is a young variable associated with the dark cloud Lynds …

UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of
stellar light by circumstellar dust. GM Cephei is such a UXor in the young (∼ 4 Myr) open …

ABSTRACT GM Cephei (GM Cep), in the young (∼ 4 Myr) open cluster Trumpler 37, has
been known to be an abrupt variable and to have a circumstellar disk with a very active …

Context. The Cep OB2 region, with its two intermediate-aged clusters Tr 37 and NGC 7160,
is a paradigm of sequential star formation and an ideal site for studies of protoplanetary disk …

This paper reports results from our long-term BV (RI) c photometric CCD observations of
eight pre-main sequence stars collected from 2008 June to 2022 October. These stars are …

Results from UBVRI photometric observations of the pre-main sequence star GM Cep
obtained in the period 2011 April–2014 August are reported in the paper. Presented data …

The dissertation presents result from study of Pre-main sequence (PMS) stars that are in the
earliest stages of stellar evolution. These young stellar objects are still in the process of …
