Most exoplanets are and have been detected by the transit method. Maybe, we can improve the method even further by drawing conclusions from the recent Venus transits in 2004 and 2012.
The years of 2014 and 2015 may well be known as the time when our exploration of the solar system truly took off, as we explored asteroids, comets, and minor planets. Here’s a look back at what we’ve accomplished in the last year, and what we’re about to achieve in the year to come.
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.
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?
Only the combined effort of observational and theoretical methods can really bring us to a more thorough understanding of the Universe throughout all spatial scales. The authors of today’s paper use and adapt the moving-mesh fluid mechanics code AREPO to function with protoplanetary disks and test its imprint on the potential of planets to open up gaps in the surrounding gas.
Chondrules are among the oldest components of the solar system and give insight in the solar system’s earliest phase. But how are they formed? In shocks? That seems to be at least difficult.
