Photometric and spectroscopic study of five pre-main sequence stars in the vicinity of NGC 7129
We present results from long-term optical photometric and spectroscopic
observations of five pre-main sequence stars, located in the vicinity of the
bright nebula NGC 7129. We obtained UBVRI photometric observations in the
field centered on the star V391 Cep, north-west of the bright nebula NGC
7129. Our multicolor CCD observations spanned the period from February 1998
to November 2016. At the time of our photometric monitoring, a total of
thirteen medium-resolution optical spectra of the stars were obtained. The
results from our photometric study show that all stars exhibit strong
variability in all optical passbands. Long-term light curves of the five
stars indicate the typical classical T Tauri star variations in brightness
with large amplitudes. We did not find any reliable periodicity in the
brightness variations of all five stars. The results from spectral
observations showed that all studied stars can be classified as classical T
Tauri stars with rich emission line spectra and strong variability in
profiles and intensity of emission lines.
期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
