On the formation of terrestrial planets between two massive planets: The case of 55 Cancri
Lei Zhou, Rudolf Dvorak, Li-Yong Zhou
Considering the huge computational resources required by smoothed particle hydrodynamics (SPH) simulations and the overestimation of post-collision materials from perfect merging,…
Theoretical Studies of Comets in the 55 Cancri System
Rudolf Dvorak, Birgit Loibnegger, Manfred Cuntz
We present orbital integrations for various Jupiter family comets (JFCs) in the 55 Cancri system. This star is known to possess (at least) five planets with masses ranging from sup…
A systematic survey of the dynamics of Uranus Trojans
Lei Zhou, Li-Yong Zhou, Rudolf Dvorak +1
We aim to locate the stability region for Uranus Trojans (UT hereafter) and find out the dynamical mechanisms responsible for the structures in the phase space. Using the spectral…
On the Dynamics of Comets in Extrasolar Planetary Systems
Rudolf Dvorak, Birgit Loibnegger, Manfred Cuntz
Since very recently, we acquired knowledge on the existence of comets in extrasolar planetary systems. The formation of comets together with planets around host stars now seems evi…
Orbital Stability of Earth Trojans
Lei Zhou, Yang-Bo Xu, Li-Yong Zhou +2
The only discovery of Earth Trojan 2010 TK and the subsequent launch of OSIRIS-REx motive us to investigate the stability around the triangular Lagrange points and …
Exocomets in the 47 UMa System: Theoretical Simulations including Water Transport
Manfred Cuntz, Birgit Loibnegger, Rudolf Dvorak
Motivated by ongoing discoveries of features (most likely) attributable to exocomets in various systems, this study examines the dynamics of possible comets around 47 UMa. Based on…
