Demographics of transition objects

Demographics of Transition Objects

The unusual properties of transition objects (young stars with an optically thin inner disc surrounded by an optically thick outer disc) suggest that significant disc evolution has occured in these systems. We explore the nature of these systems by examining their demographics, specifically their stellar accretion rates Ṁ∗ and disc masses Mdisc compared to those of accreting T Tauri stars of co...

Deformation Transition Graphs in Forming Operations of Rheological Objects

1 I n t r o d u c t i o n In food industry, we can find many manipulative operations that deal with deformable rheologic materials such as dough, paste, jelly, and meat. Most these operations are done by humans. Especially, operations with large deformation of rheologic objects depend upon humans. For example, forming of pizza dough to a thin circular shape is performed by humans while extensio...

Dynamical and physical properties of comet–asteroid transition objects

In the last few years it has been pointed out that, from both physical and dynamical point of view, it is becoming more and more difficult to distinguish comets from asteroids and indeed there are some examples of small bodies first designated as comets which had, later, to be reclassified as asteroids and vice versa (Hartmann et al., 1990; McFadden, 1994). In order to investigate the evolution...
