Dynamical history of the observed long-period comets [PDF]
Astronomy & Astrophysics, 2001 We present results of some numerical studies on the dynamical history of a large number of observed long-period comets. In our investigations we include all comets with good quality orbits. We calculated barycentric, original orbital elements for comets at a distance of 250 AU from the Sun and then followed the motion of each comet (elliptic orbits ...

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review
Addiction, EarlyView.Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

A JWST Study of the Remarkable Oort Cloud Comet C/2017 K2 (PanSTARRS)
The Planetary Science JournalComets, during their journeys into the inner solar system, deliver volatile gases, organics, and particulates into their comae that provide crucial information for assessing the physicochemical conditions in the outer disk from which they formed. Here we

EVOLUTIONARY TRACKS OF SHORT-PERIODIC METEOR SWARMS
Odessa Astronomical Publications, 2017 The relations of the meteor streams with comets and asteroids are determined by means of the physical and dynamic properties of these bodies. The mathematical model is considered for the short-periodic meteor stream, the particles of which are ejected ...
