The enigmatic multiple star VV Ori
Edwin Budding, John Southworth, Kresimir Pavlovski +6
New photometry, including TESS data, have been combined with recent spectroscopic observations of the Orion Ib pulsating triple-star system VV Ori. This yields a revised set of abs…
The First Multiband Photometric Light Curve Solutions of the V Gru Binary System from the Southern Hemisphere
Mehmet Tanriver, Atila Poro, Ahmet Bulut +2
The first multiband photometric solutions of the short-period V Gru eclipsing binary from the southern hemisphere is presented in this study. Light curves of the system were observ…
V410 Puppis: A useful laboratory for early stellar evolution
Ahmet Erdem, Derya Surgit, Burcu Ozkardes +6
New spectrometric (HERCULES) and ground-based multi-colour photometric data on the multiple star V410 Puppis are combined with satellite photometry (HIPPARCOS and TESS), as well as…
The Photometric Study of Six W UMa Systems and Investigation of the Mass-Radius Relations for Contact Binary Stars
Atila Poro, Ehsan Paki, Mark G. Blackford +13
We present the photometric analysis of six short-period systems (EI Oct, V336 TrA, NX Boo, V356 Boo, PS Boo, and V2282 Cyg). This is the first photometric analysis of these systems…
Comprehensive analysis of southern eclipsing systems with pulsating components: The cases of HM Pup, V632 Sco and TT Vel
A. Liakos, D. J. W. Moriarty, M. G. Blackford +4
This work presents an extensive analysis of the properties of three southern semi-detached eclipsing binaries hosting a pulsating component, namely HM Pup, V632 Sco, and TT Vel. Sy…
Towards a consistent model of the hot quadruple system HD 93206 = QZ Carinae - I. Observations and their initial analyses
P. Harmanec, P. Zasche, M. Brož +17
The hot nine-component system HD 93206, which contains a gravitationally bounded eclipsing Ac1+Ac2 binary (~d) and a spectroscopic Aa1+Aa2 (~d) binary can provi…
The New Ephemeris and Light Curve Analysis of V870 Ara by the Ground-Based and TESS Data
Atila Poro, Mark G. Blackford, Fatemeh Davoudi +4
New CCD photometric observations and their investigation of the W UMa-type binary, V870 Ara, are presented. Light curves of the system were taken through BVI filters from the Conga…
BG Ind: the nearest doubly eclipsing, compact hierarchical quadruple system
T. Borkovits, S. A. Rappaport, P. F. L. Maxted +9
BG Ind is a well studied, bright, nearby binary consisting of a pair of F stars in a 1.46-day orbit. We have discovered in the TESS lightcurve for TIC 229804573 (aka BG Ind) a seco…
BVRI Photometric Observations, Light Curve Solutions and Orbital Period Analysis of BF Pav
Atila Poro, Fahri Alicavus, Eduardo Fernández-Lajús +7
A new ephemeris, period change analysis and light curve modeling of the W UMa-type eclipsing binary BF Pav are presented in this study. Light curves of the system taken in BVRI fil…
QZ Carinae Orbit of the Two Binary Pairs
Mark Blackford, Stan Walker, Edwin Budding +9
We present an updated O-C diagram of the light-time variations of the eclipsing binary (component B) in the system QZ Carinae as it moves in the long-period orbit around the non-ec…
Absolute Parameters of YOung Stars: GG Lup and mu^1 Sco
Edwin Budding, Roger Butland, Mark Blackford
New high-resolution spectroscopy and photometry, together with literature data, on the Gould's Belt close binary systems GG Lup and Sco are presented and analysed. In t…
