Starspots and spin - orbit alignment for Kepler cool host stars
The angle between the spin axis of the host star and the orbit of its planets (i.e., the stellar obliquity) is precious information about the formation and evolution of exoplanetary systems. Measurements of the Rossiter-McLaughlin effect revealed that many stars that host a hot-Jupiter have high obliquities, suggesting that hot-Jupiter formation involves excitation of orbital inclinations. In t...
متن کاملmass objects orbit mirror stars ?
Do " isolated " planetary mass objects orbit mirror stars? Abstract We propose that the " isolated " planetary mass objects observed by Zapatero Osorio et al in the σ Orionis cluster might actually be in orbit around invisible stellar mass companions such as mirror stars. Mirror matter is expected to exist if parity is an unbroken symmetry of nature. Future observations can test this idea by lo...
متن کاملRelative orientation of orbits in triple stars
Statistical analysis of the relative alignment of inner and outer orbits in triple systems resulting from a dynamical decay of small-N clusters (N ≤ 10) is presented and compared to the statistics of real multiple stars. The distribution of the relative angle Φ between the angular momentum vectors of inner and outer orbits in triple stars formed by decay is shown to depend on the initial cluste...

متن کاملSmall strange stars and marginally stable orbit in Newtonian theory
It is shown that for very rapidly rotating low mass strange stars the marginally stable orbit is located above the stellar surface. This effect is explained by the very important role of the oblateness of the rotating strange star. The comparison with some “academic” examples is presented. This feature is purely Newtonian in its nature and has nothing to do with relativistic marginally stable o...
