ExoClock Project IV: A homogeneous catalogue of 620 updated exoplanet ephemerides

A. Kokori, A. Tsiaras, G. Pantelidou +323

The ExoClock project is an open platform aiming to monitor exoplanets by integrating observations from space and ground based telescopes. This study presents an updated catalogue o…

Optical Variability Correlated with X-ray Spectral Transition in the Black-Hole Transient ASASSN-18ey = MAXI J1820+070

Keito Niijima, Mariko Kimura, Yasuyuki Wakamatsu +49

How a black hole accretes matter and how this process is regulated are fundamental but unsolved questions in astrophysics. In transient black-hole binaries, a lot of mass stored in…

Massive search of spot- and facula-crossing events in 1598 exoplanetary transit lightcurves

R. V. Baluev, E. N. Sokov, I. A. Sokova +40

We developed a dedicated statistical test for a massive detection of spot- and facula-crossing anomalies in multiple exoplanetary transit lightcurves, based on the frequentist -…

GJ 3470 c: A Saturn-like Exoplanet Candidate in the Habitable Zone of GJ 3470

Phillip Scott, Bradley Walter, Quanzhi Ye +12

We report the discovery of a new exoplanet candidate orbiting the star GJ 3470. A total of three transits were detected by OKSky Observatory: the first one on December 23, 2019, th…

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…

Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle

B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58

The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…
