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…
The Formation of Habitable Planets in the Four-Planet System HD 141399
R. Dvorak, B. Loibnegger, L. Y. Zhou +1
The presented work investigates the possible formation of terrestrial planets in the habitable zone (HZ) of the exoplanetary system HD 141399. In this system the HZ is located appr…
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…
Stability of a rotating asteroid housing a space station
Thomas I. Maindl, Roman Miksch, Birgit Loibnegger
Today there are numerous studies on asteroid mining. They elaborate on selecting the right objects, prospecting missions, potential asteroid redirection, and the mining process its…
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…
Case Studies of Exocomets in the System of HD 10180
Birgit Loibnegger, Rudolf Dvorak, Manfred Cuntz
The aim of our study is to investigate the dynamics of possible comets in the HD 10180 system. This investigation is motivated by the discovery of exocomets in various systems, esp…
On the probability of the collision of a Mars-sized planet with the Earth to form the Moon
Rudolf Dvorak, Birgit Loibnegger, Thomas I. Maindl
The problem of the formation of the Moon is still not explained satisfactorily. While it is a generally accepted scenario that the last giant impact on Earth between some 50 to 100…
