Possibilities of life around Alpha Centauri B
We make a preliminary assessment on the habitability of potential rocky exoplanets around Alpha Centauri B. We use several indexes: the Earth Similarity Index, a mathematical model for photosynthesis, and a biological productivity model. Considering the atmospheres of the exoplanets similar to current Earth’s atmosphere, we find consistent predictions of both the Earth Similarity Index and the ...
متن کاملA new seismic analysis of Alpha Centauri
Models of α Cen A & B have been computed using the masses determined by Pourbaix et al. (2002) and the data derived from the spectroscopic analysis of Neuforge and Magain (1997). The seismological data obtained by Bouchy and Carrier (2001, 2002) do help improve our knowledge of the evolutionary status of the system. All the constraints are satisfied with a model which gives an age of about 6 Gy...
متن کاملMcROSS-A multi-computer programming system* by ROBERT H. THOMAS and D. AUSTIN HENDERSON
This paper describes an experimental "distributed" programming system which makes it possible to create multi-computer programs and to run them on computers connected by the ARPA computer network (ARPANET).1 The programming system, which is called McROSS (for Multi-Computer Route Oriented Simulation System), is an extension of a singlecomputer simulation system for modelling air traffic situati...

متن کاملPlanet formation in the habitable zone of alpha Centauri B
Recent studies have shown that alpha Centauri B might be, from an observational point of view, an ideal candidate for the detection of an Earth-like planet in or near its habitable zone (0.5-0.9AU). We study here if such habitable planets can form, by numerically investigating the planet-formation stage which is probably the most sensitive to binarity effects: the mutual accretion of km-sized p...
