Could the properties of an M-dwarf that might make it inhospitable also give it transformative powers? Could the star’s gravity and violence strip away a planet’s thick atmosphere, or envelope, to reveal a habitable core?
The recent discoveries of alien worlds seemingly rich in carbon reveal a lot of diverse information about the history and further evolutionary paths of exoplanets. However, a correct physical understanding of the investigated systems is crucial for getting the most out of incoming data and is an area of very active research. Therefore, the theoretical modeling of exoplanetary systems must be advanced to a state which includes the long-term evolution of the distribution of detectable molecular species in the planet forming environment.
Water is essential for life, but where does it come from? Read on and learn that a significant amount is inherited from the interstellar medium.
Habitable zone estimations take the climate regulation of the carbon cycle into account. But are we drawing the edges of the habitable zone too wide?
Yang et al. use climate models to investigate whether rocky exoplanets around M-stars can retain their oceans in the face of tidal locking.
Asteroids and volcanoes are familiar harbingers of global doom. But what about Gamma Ray Bursts? Is another doomsday lurking?
