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…
Spectroscopic Observations of Selected Planetary Nebulae from the HASH Database
Utkan Temiz, Nazım Aksaker, Aysun Akyuz
We conducted research on the classification and physical properties of 10 objects from the HASH (Hong Kong/Australian Astronomical Observatory/Strasbourg Observatory H-alpha Planet…
Investigation of the Connection Between X-ray Binaries and Compact Star Clusters in NGC 628
Senay Avdan, Aysun Akyuz, Seda Acar +3
We investigated for a possible connection between the types of X-ray binaries (XRBs) and the properties of compact star clusters in the nearby galaxy NGC 628. Using {\it Chandra} a…
X-ray spectral and optical properties of a ULX in NGC 4258 (M106)
Hasan Avdan, Senay Avdan, Aysun Akyuz +3
We study the X-ray and optical properties of the ultraluminous X-ray source (ULX) X-6 in the nearby galaxy NGC 4258 (M106) based on the archival {\it XMM-Newton}, {\it Chandra}, {\…
Emission-Line Fluxes of Northern Planetary Nebulae
N. Aksaker, S. K. Yerli, Ü. Kızıloğlu +1
We present long slit spectrophotometric emission line fluxes of bright and extended (<5 arcsec in diameter) Planetary Nebulae (PNe) selected from Acker et al. 1992 catalog with sui…
