Presentation of Kryoneri Observatory at the Europlanet Telescope Network Science Workshop
A poster presentation on the capabilities of the Kryoneri telescope regarding its instrumentation was given at the Europlanet Telescope Network Science Workshop, which took place (virtually) between February 9-11, 2022.
Constraints on the structure and seasonal variations of Triton’s atmosphere from the 5 October 2017 stellar occultation and previous observations
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of which yielded a central flash detection. We aimed at constraining Triton's atmospheric structure and the seasonal variations of its atmospheric pressure since the Voyager 2 epoch (1989). We also derived the shape of the lower atmosphere from central flash analysis.
The National Observatory of Athens monitors the flyby of asteroid 7482 (1994 PC1)
The Institute of Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens (NOA) successfully observed the flyby of asteroid 7482 (1994 PC1) with the 1.2m Kryoneri telescope.
Extension of NELIOTA lunar impact observations through the CARMEN project
We are happy to announce the extension of the NELIOTA project for two years. Starting in August 2021, the project is funded by ESA through the project Consolidating Activities Regarding Moon, Earth and NEOs (CARMEN, contract No. 4000134667/21/D/MRP), coordinated by 6ROADS, until July 2023.
Series of outreach events at the Kryoneri Observatory – Summer 2021
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.
Optical observations of the BepiColombo spacecraft as a proxy for a potential threatening asteroid
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 ...
IAASARS hosted a virtual tour of Kryoneri Observatory
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.
National Observatory of Athens and the Peloponnese Region signed partnership agreement for the upgrade of the Kryoneri Observatory
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.
CoBiToM project – I. Contact binaries towards merging
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 ...
