Substellar companions and isolated planetary mass objects from protostellar disc fragmentation
Self-gravitating protostellar discs are unstable to fragmentation if the gas can cool on a time scale that is short compared to the orbital period. We use a combination of hydrodynamic simulations and N-body orbit integrations to study the long term evolution of a fragmenting disc with an initial mass ratio to the star of M disc /M * = 0.1. For a disc which is initially unstable across a range ...

متن کاملDo “ isolated ” planetary mass objects orbit invisible stellar mass companions ?
Do " isolated " planetary mass objects orbit invisible stellar mass companions? Abstract We propose that the " isolated " planetary mass objects observed by Zapa-tero Osorio et al in the σ Orionis cluster might actually be in orbit around invisible stellar mass companions such as mirror stars. The existence of such objects can be motivated by the dark matter problem and the observation of MACHO...
متن کاملIn-Situ Mass Spectrometry of Atmosphereless Planetary Objects
Science Goals Dust particles, like photons, carry information from remote sites in space and time. From knowledge of the dust particles’ birthplace and their composition, we can learn about the remote environment out of which the particles were formed. This approach is called “Dust Astronomy” which is carried out by means of a dust telescope in space. Dust Astronomy provides a novel method to d...
متن کاملGrouping Objects to Homogeneous Classes Satisfying Requisite Mass
Grouping datasets plays an important role in many scientific researches. Depending on data features and applications, different constrains are imposed on groups, while having groups with similar members is always a main criterion. In this paper, we propose an algorithm for grouping the objects with random labels, nominal features having too many nominal attributes. In addition, the size constra...
