Low-cost precursor of an interstellar mission
René Heller, Guillem Anglada-Escudé, Michael Hippke +1
The solar photon pressure provides a viable source of thrust for spacecraft in the solar system. Theoretically it could also enable interstellar missions, but an extremely small ma…
Habitability Models for Planetary Sciences
Abel Méndez, Edgard G. Rivera-Valentín, Dirk Schulze-Makuch +32
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
Habitability of the early Earth: Liquid water under a faint young Sun facilitated by strong tidal heating due to a closer Moon
René Heller, Jan-Peter Duda, Max Winkler +2
Geological evidence suggests liquid water near the Earth's surface as early as 4.4 billion years ago when the faint young Sun only radiated about 70% of its modern power output. At…
Transit least-squares survey -- III. A transit candidate in the habitable zone of Kepler-160 and a nontransiting planet characterized by transit-timing variations
René Heller, Michael Hippke, Jantje Freudenthal +3
The Sun-like star Kepler-160 (KOI-456) has been known to host two transiting planets, Kepler-160 b and c, of which planet c shows substantial transit-timing variations (TTVs). We u…
A possible transit of a disintegrating exoplanet in the nearby multiplanet system DMPP-1
Mark H. Jones, Carole A. Haswell, John R. Barnes +2
We analyse TESS photometry of DMPP-1 (HD 38677; TIC 66560666), a nearby F8V star hosting hot super-Earth planets and a warm Neptune. Using the Transit Least Squares algorithm and o…
Habitability is a continuous property of nature
René Heller
In their recent comment, Cockell et al. argue that the habitability of an environment is fundamentally a binary property; that is to say, an environment can either support the meta…
