The (time-independent) Schrödinger equation for atomistic systems is solved by using the adiabatic potential energy curves (PECs) and associated approximation. In cases where interactions between electronic states become important, nonadiabatic effects are taken into account via derivative couplings (DDRs), also known as (NACs). For diatomic molecules, corresponding PECs in representation characterized avoided crossings. alternative to approach diabatic obtained a unitary transformation of...
Asteroid 2024 XA$_1$ was discovered on 3 December at 05:54 UTC by the Bok telescope in Kitt Peak, Arizona, and impacted Earth about 10 hours later over a remote area of Sakha Republic (Russia). The estimated size object one meter, atmospheric entry produced bright fireball that captured webcam several eyewitnesses. first impact alert issued 07:50 Meerkat Guard European Space Agency, which triggered subsequent follow-up observations confirmed both to be real occurrence with Earth. Here we...
Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speeds. Understanding their properties, including rotation state, is crucial for assessing risks and mitigation strategies. Traditional photometric methods face challenges in accurately collecting data fast-moving NEOs. Aims. This study introduces innovative approach to aperture photometry, tailored analyzing trailed images of Our primary aim extract state information fast rotators. Methods. We applied...

Circular aperture photometry, is a crucial method utilized in astronomical observations for measuring the flux emitted by point sources [1]. Its utility spans diverse phenomena, encompassing tasks such as determining absolute magnitude and spin period of asteroids [2]. In conducting traditional circular photometry on objects motion, it's essential to adjust exposure time prevent both moving object stars from appearing elongated image. When dealing with near-Earth (NEOs) challenging...
The NEO Coordination Centre (NEOCC) of the European Space Agency is an operational centre that, among other activities, computes orbits near-Earth objects and their probabilities impact with Earth. NEOCC started providing information about in 2012 on a dedicated web portal, accessible at https://neo.ssa.esa.int/. Since beginning phase, many developments improvements have been implemented regarding software, data provided, portal. One most important upgrades that now independently through...
The (stationary) Schr\"{o}dinger equation for atomistic systems is solved using the adiabatic potential energy curves (PECs) and associated approximation. Despite being very simplistic, this approach powerful used in nearly all practical applications. In cases when interactions between electronic states become important, non-adiabatic effects are taken into account via derivative couplings (DDRs), also known as (NACs). For diatomic molecules, corresponding PECs representation characterized...
