Revisiting Planetary Systems in Okayama Planet Search Program: A new long-period planet, RV astrometry joint analysis, and multiplicity-metallicity trend around evolved stars
Huan-Yu Teng, Bun'ei Sato, Masayuki Kuzuhara +15
In this study, we revisit 32 planetary systems around evolved stars observed within the framework of the Okayama Planet Search Program and its collaborative framework of the EAPS-N…
Homogeneous Transit Timing Analyses of Ten Exoplanet Systems
Ö. Baştürk, E. M. Esmer, S. Yalçınkaya +19
We study the transit timings of 10 exoplanets in order to investigate potential Transit Timing Variations (TTVs) in them. We model their available ground-based light curves, some p…
Analysis of the Most Precise Light Curves of HAT-P-36 Detrended From Spot Signals
Selçuk Yalçınkaya, Özgür Baştürk, Fadel El Helweh +6
We study the most precise light curves of the planet-host HAT-P-36 that we obtained from the ground primarily with a brand-new 80 cm telescope very recently installed at Ankara Uni…
The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert
S. Dreizler, I., J. +134
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…
Starspot activity and differential rotation in KIC 11560447
Emre Isik, Ibrahim Ozavci, Hakan V. Senavci +4
Using high-precision photometry from the \textit{Kepler} mission, we investigate patterns of spot activity on the K1-type subgiant component of KIC 11560447, a short-period late-ty…
Recurrent starspot activity and differential rotation in KIC 11560447
İbrahim Özavci, Hakan V. Şenavci, Emre Işik +4
We present a detailed analysis of surface inhomogeneities on the K1-type sub-giant component of the rapidly rotating eclipsing binary KIC 11560447, using high-precision Kepler ligh…
Photometric, Spectroscopic and Orbital Period Study of Three Early Type Semi-detached Systems: XZ Aql, UX Her and AT Peg
S. Zola, O. Basturk, A. Liakos +6
In this paper we present a combined photometric, spectroscopic and orbital period study of three early-type eclipsing binary systems: XZ Aql, UX Her, and AT Peg. As a result, we ha…
The Absolute Parameters of The Detached Eclipsing Binary V482 Per
Ozgur Basturk, Staszek Zola, Alexios Liakos +6
We present the results of the spectroscopic, photometric and orbital period variation analyses of the detached eclipsing binary \astrobj{V482~Per}. We derived the absolute paramete…
Physical Parameters of Some Close Binaries: ET Boo, V1123 Tau, V1191 Cyg, V1073 Cyg and V357 Peg
F. Ekmekçi, A. Elmaslı, M. Yılmaz +7
With the aim of providing new and up-to-date absolute parameters of some close binary systems, new BVR CCD photometry was carried out at the Ankara University Observatory (AUG) for…
