N-body interactions and collisions in circumstellar disks for planar and inclined binary star configurations
Maximilian Zimmermann, Elke Pilat-Lohinger
The discovery of exoplanets in binary star systems-now numbering about 850 of the nearly 4,600 known exoplanet systems-raises questions about whether observational bias or stellar…
Habitable Zones in Binary Star Systems: A Zoology
Siegfried Eggl, Nikolaos Georgakarakos, Elke Pilat-Lohinger
Several concepts have been brought forward to determine where terrestrial planets are likely to remain habitable in multi-stellar environments. Isophote-based habitable zones, for…
Fear the Shadows of the Giants: On Secular Perturbations in Circumstellar Habitable Zones of Double Stars
Ákos Bazsó, Elke Pilat-Lohinger
After the detection of extrasolar planets in binary and multiple star systems questions arose about their dynamics and habitability. In this study we investigate a five-dimensional…
Analytical estimates of secular frequencies for binary star systems
Ákos Bazsó, Elke Pilat-Lohinger
Binary and multiple star systems are extreme environments for the formation and long-term presence of extrasolar planets. Circumstellar planets are subject to gravitational perturb…
Water transport to circumprimary habitable zones from icy planetesimal disks in binary star systems
D. Bancelin, E. Pilat-Lohinger, T. I. Maindl +1
So far, more than 130 extrasolar planets have been found in multiple stellar systems. Dynamical simulations show that the outcome of the planetary formation process can lead to dif…
The influence of orbital resonances on the water transport to objects in the circumprimary habitable zone of binary star systems
D. Bancelin, E. Pilat-Lohinger, T. I. Maindl +2
We investigate the role of secular and mean motion resonances on the water transport from a belt of icy asteroids onto planets or embryos orbiting inside the circumprimary habitabl…
On the ultraviolet anomalies of the WASP-12 and HD 189733 systems: Trojan satellites as a plasma source
K. G. Kislyakova, E. Pilat-Lohinger, B. Funk +6
We suggest an additional possible plasma source to explain part of the phenomena observed for the transiting hot Jupiters WASP-12b and HD 189733b in their ultraviolet (UV) light cu…
Dynamics and habitability in circumstellar planetary systems of known binary stars
Ákos Bazsó, Elke Pilat-Lohinger, Siegfried Eggl +3
We present a survey on exoplanetary systems of binary stars with stellar separations less than 100 au. For a sample of 11 binaries that harbour detected circumstellar giant planets…
Asteroid flux towards circumprimary habitable zones in binary star systems: II. Dynamics
D. Bancelin, E. Pilat-Lohinger, A. Bazso
Secular and mean motion resonances (MMR) are effective perturbations for shaping planetary systems. In binary star systems, they play a key role during the early and late phases of…
Water delivery in the Early Solar System
Rudolf Dvorak, Siegfried Eggl, Áron Süli +3
As part of the national scientific network 'Pathways to Habitable Worlds' the delivery of water onto terrestrial planets is a key question since water is essential for the developm…
Can there be additional rocky planets in the Habitable Zone of tight binary stars with a known gas giant?
Barbara Funk, Elke Pilat-Lohinger, Siegfried Eggl
Locating planets in HabitableZones (HZs) around other stars is a growing field in contemporary astronomy. Since a large percentage of all G-M stars in the solar neighbourhood are e…
Impact flux of asteroids and water transport to the habitable zone in binary star systems
D. Bancelin, E. Pilat-Lohinger, S. Eggl +1
By now, observations of exoplanets have found more than 50 binary star systems hosting 71 planets. We expect these numbers to increase as more than 70% of the main sequence stars i…
The role of dynamics on the habitability of an Earth-like planet
E. Pilat-Lohinger
From the numerous detected planets outside the Solar system, no terrestrial planet comparable to our Earth has been discovered so far. The search for an Exo-Earth is certainly a bi…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
Dynamics and Habitability in Binary Star Systems
Siegfried Eggl, Nikolaos Georgakarakos, Elke Pilat-Lohinger
Determining planetary habitability is a complex matter, as the interplay between a planet's physical and atmospheric properties with stellar insolation has to be studied in a self…
Astrophysical Conditions for Planetary Habitability
M. Guedel, R. Dvorak, N. Erkaev +7
With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal…
Impact inducted surface heating by planetesimals on early Mars
T. I. Maindl, R. Dvorak, H. Lammer +7
We investigate the influence of impacts of large planetesimals and small planetary embryos on the early Martian surface on the hydrodynamic escape of an early steam atmosphere that…
Disc-protoplanet interaction Influence of circumprimary radiative discs on self-gravitating protoplanetary bodies in binary star systems
M. Gyergyovits, S. Eggl, E. Pilat - Lohinger +1
Context. More than 60 planets have been discovered so far in systems that harbour two stars, some of which have binary semi-major axes as small as 20 au. It is well known that the…
Detectability of Earth-like Planets in Circumstellar Habitable Zones of Binary Star Systems with Sun-like Components
Siegfried Eggl, Nader Haghighipour, Elke Pilat-Lohinger
Given the considerable percentage of stars that are members of binaries or stellar multiples in the Solar neighborhood, it is expected that many of these binaries host planets, pos…

Siegfried Eggl, Elke Pilat-Lohinger, Barbara Funk +2
Binary and multiple systems constitute more than half of the total stellar population in the Solar neighborhood (Kiseleva-Eggleton and Eggleton 2001). Their frequent occurrence as…
