The Institute of Astronomy, Astrophysics, Space Applications and Remote Sensing of the National Observatory of Athens organizes for the summer months, astronomy evenings at the Kryoneri Observatory in Corinth.
We present the results of our ground-based astrometric observation campaign of BepiColombo during its Earth fly-by on 2020 April 10. The observational circumstances induced by the fly-by geometry made this event an excellent proxy for a close fly-by or an imminent impact of a natural body with a diameter of a few meters, with the added benefit of having a ground-truth orbit (from radio tracking) to compare with our purely ...
On the evening of April 15th, IAASARS hosted a virtual tour of Kryoneri Observatory, which included live viewing of the Moon through the 1.2 meter telescope, a presentation of the facilities and the lunar monitoring research program NELIOTA.
The program agreement was signed between the National Observatory of Athens and the Peloponnese Region for the upgrade of the infrastructure of the Kryoneri Observatory with funding from the region of Peloponnesus of 3M euro. The first pillar of the project is the further upgrade of the Kryoneri telescope, thus increasing its observational capabilities. The second pillar focuses on the diffusion of science by creating an exhibition space, where the visitor will be able to take a historical walk in the contribution of this telescope to the science of Astronomy.
Binary and multiple stellar systems are numerous in our solar neighbourhood with 80 per cent of the solar-type stars being members of systems with high order multiplicity. The Contact Binaries Towards Merging (CoBiToM) Project is a programme that focuses on contact binaries and multiple stellar systems, as a key for understanding stellar nature. The goal is to investigate stellar coalescence and merging processes, as the final state of stellar evolution of low-mass contact binary systems. Obtaining observational data of approximately 100 eclipsing binaries and multiple systems and more than 400 archival systems, the programme aspires to give insights for their physical and orbital parameters and their temporal variations, e.g. the orbital period ...
The present work contains light curve, spectroscopic, and asteroseismic analyses for KIC 04851217 and KIC 10686876. These systems are detached eclipsing binaries hosting a pulsating component of δ Scuti type and have been observed with the unprecedented accuracy of the Kepler space telescope. Using ground-based spectroscopic observations, the spectral types of the primary components of the systems were estimated as A6V and A5V for KIC 04851217 and KIC 10686876, respectively, with an uncertainty of one subclass. The present spectral classification, together with literature radial velocity curves, were used to model the light curves of the systems and, therefore, to calculate the absolute parameters of their ...

There have been 79 lunar impact flashes observed with the 1.2 m Kryoneri telescope in Greece. The masses of the meteoroids range between 0.7 g and 8 kg, and their respective sizes between 1 and 20 cm, depending on their assumed density, impact velocity, and luminous efficiency. We find a strong correlation between the observed magnitudes ...
Open night at Kryoneri Observatory 2019 cheska-lekarna.com On July 20th, the National Observatory of Athens and the Youth Cultural Society of Kryoneri hosted an open night at Kryoneri Observatory. Over 300 people attended the event, which included a tour of the 1.2m Kryoneri telescope, viewing of the Moon, planets and other celestial [...]
