Migration and Evolution of giant ExoPlanets (MEEP). III. Twenty-Nine Giant Planets from the TESS Mission
Jack Schulte, Joseph E. Rodriguez, David W. Latham +97
We present the discovery and characterization of 29 hot and warm Jupiter systems transiting bright () FGK stars using TESS data and ground-based photometry and spectrosco…
Assessing the Impact of High-Resolution Imaging on Statistical Validation of TESS Planet Candidates
Michael Collier, Steven Giacalone, Brian Derfer +38
High-resolution imaging is widely used to constrain false-positive scenarios in exoplanet validation, but it is a finite follow-up resource that reaches only a subset of candidates…
Classification of Eclipsing Binary Light Curves in Gaia DR3: A Machine Learning Approach
Bedri Keskin, Özgür Baştürk
Gaia Data Release 3 (DR3) presents a unique dataset with approximately 2.1 million eclipsing binary star candidates. The unsustainability of manually classifying such a large volum…
Looking For Timing Variations in the Transits of 16 Exoplanets
S. Yalçınkaya, E. M. Esmer, Ö. Baştürk +27
We update the ephemerides of 16 transiting exoplanets using our ground-based observations, new TESS data, and previously published observations including those of amateur astronome…
Transit timing variation analysis of the low-mass brown dwarf KELT-1 b
Ö. Baştürk, J. Southworth, S. Yalçınkaya +8
We investigate whether there is a variation in the orbital period of the short-period brown dwarf-mass KELT-1\,b, which is one of the best candidates to observe orbital decay. We o…
Investigation of an orbital decay and global modeling of the planet WASP-43 b
Fatemeh Davoudi, Özgür Baştürk, Selçuk Yalçınkaya +2
WASP-43 b is one of the most important candidates for detecting an orbital decay. We investigate pieces of evidence for this expectation as variations in its transit timings, based…
The ultra-hot-Jupiter KELT-16 b: Dynamical Evolution and Atmospheric Properties
L. Mancini, J. Southworth, L. Naponiello +15
We present broad-band photometry of 30 planetary transits of the ultra-hot Jupiter KELT-16b, using five medium-class telescopes. The transits were monitored through standard B, V,…
Discovery of a young low-mass brown dwarf transiting a fast-rotating F-type star by the Galactic Plane eXoplanet (GPX) survey
P. Benni, A. Y. Burdanov, V. V. Krushinsky +64
We announce the discovery of GPX-1 b, a transiting brown dwarf with a mass of and a radius of , the first sub-stell…
Discovery of a pre-cataclysmic binary with unusual chromaticity of the eclipsed white dwarf by the GPX Survey
Vadim Krushinsky, Paul Benni, Artem Burdanov +14
We report the discovery of a relatively bright eclipsing binary system, which consists of a white dwarf and a main sequence K7 star with clear signs of chromospheric and spot activ…
Homogeneously derived transit timings for 17 exoplanets and reassessed TTV trends for WASP-12 and WASP-4
R. V. Baluev, E. N. Sokov, H. R. A. Jones +34
We homogeneously analyse photometric measurements for transit lightcurves belonging to exoplanet hosts. The photometric data cover years…
KPS-1b: the first transiting exoplanet discovered using an amateur astronomer's wide-field CCD data
Artem Burdanov, Paul Benni, Eugene Sokov +19
We report the discovery of the transiting hot Jupiter KPS-1b. This exoplanet orbits a V=13.0 K1-type main-sequence star every 1.7 days, has a mass of $M_{…
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…

This study presents elemental abundances of the early A-type supergiant HD 80057 and the late A-type supergiant HD80404. High resolution and high signal-to-noise ratio spectra publ…
Defocused Observations of Selected Exoplanet Transits with T100 in TUBITAK National Observatory of Turkey (TUG)
Ozgur Basturk, Tobias C. Hinse, Ibrahim Ozavci +2
It is crucial to determine masses and radii of extrasolar planets with high precision to have constraints on their chemical composition, internal structure and thereby their format…
