Rotation, spectral type, and albedo of the potentially hazardous asteroid (153814) 2001 WN Prior to the 2028 June close approach
Jin Beniyama, Alexey V. Sergeyev, Konstantinos Odysseas Xenos +6
The potentially hazardous asteroid (153814) 2001 WN will pass inside the lunar distance on June 26, 2028, offering a rare opportunity to characterize a kilometer-scale near-Ear…
Shape, Orientation and Colors Combined approach for Asteroids (SOCCA)
K. O. Xenos, B. Carry, J. Peloton +3
Large photometric surveys provide sparse multi-band photometry for millions of Solar System objects, offering an opportunity to jointly constrain their physical and compositional p…
Beyond the Unruh vacuum: multi-time correlations in black hole collapse and evaporation
Konstantinos Xenos, Charis Anastopoulos, Andreas F. Terzis
The black hole information paradox originates from the thermal character of Hawking radiation, which appears to erase information about the collapsing matter. However, thermality c…
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…
How does the chemical composition of solids influence the formation of planetesimals?
Konstantinos Odysseas Xenos, Bertram Bitsch, Geoffrey Andama
The formation of planetesimals is a necessary step in the formation of planets. While several mechanisms have been proposed, a local dust-to-gas ratio above unity is a strong requi…
