... Ever wonder how solar-mass stars form?. ... In order for material to accrete onto a protostar it has to lose angular momentum. The angular momentum of a large natal cloud leads to the formation of a circumstellar disk and inner accretion disk as the cloud collapses. ... Winds generated in the inner disk or close to the stellar surface (we don't know which) expel material along the disk rotation axis. ... This provides the highest resolution observational data on nearby young stars. ...

... Indeed, one alteration of orbits can be the outright ejection of a planet. When several big planets are orbiting a star under each other's influence, the system is inherently unstable. ... We know of no good reason why the smallest objects with fusion should have the same mass as the smallest objects that can form by themselves. ... 6) Mission Definition . ... I don't think this mission is impossible, and will suggest a definition in a future article in Mercury. ... Good luck! . ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

Quite possibly, however, the red object is the first direct image of a planet beyond our Solar System . ... The faint red object 2M1207b is therefore 100 times fainter, intrinsically, than the bright white brown dwarf 2M1207a -- a characteristic well explained by a planet roughly five times the mass of Jupiter . ...

What changed our view of Chariklo is the discovery of a ring system around it, the first such feature found around a Solar System body smaller than a gas giant planet. ... Almost certainly the rings were born when a collision with a smaller asteroid blasted millions of tonnes of debris off CharikloтАЩs surface. ... A ring system detected around the Centaur (10199) Chariklo (Braga-Rigas et al.) ...

... For moving objects such as asteroids, comets, or planets, it is useful to include ephemeris information, both to provide predicted coordinates for planning observations, and to allow accurate airmass calculations in the reductions. ... These times can be given either as Modified Julian Dates ( ), or as ordinary date strings like 1995 Jan 23.0 . To allow good interpolation, include two ephemeris entries before and two after the interval of observations. ... UT date --- column label: DATE . ...

EXPLANATION OF DANA'S FIBER TESTS ON THE 12M TELESCOPE.. ... But we know full well that this is not directly possible- the delay in the optical fiber carrying this signal will change both with temperature and to some degree with fiber bending as the telescope tracks objects or moves from one object to another. ... So we would like to identify at least one pair of single mode fibers in our bundle, whose delay changes due to antenna tracking etc are pretty well matched. ...

Influence of Asteroids and Trans-Neptunian Objects on the Motion of Major Planets and Masses of the Asteroid Main Belt and the TNO Ring . ... Perturbations from asteroids and Trans-Neptunian Objects (TNOs) produce a significant effect on the orbits of planets and should be taken into account when high-accuracy planetary ephemerides are constructed. On the other hand, from an analysis of motion of the major planets some physical parameters of the asteroids and TNOs may be obtained. ...

... The concerns here are similar to those for observing bright targets; saturation and blooming of the bright companion PSF must not impact the faint target. Also, one may need to consider subtracting the PSF of the bright object, and effects which limit the accuracy of that subtraction. If the bright companion will saturate and bloom, it will be necessary to rotate the CCD so that blooming along the CCD columns does not obliterate the faint target. ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

... no comet has been observed with an orbit that indicates that it came from interstellar space, . ... From this he proposed that comets reside in a vast cloud at the outer reaches of the solar system. ... Unfortunately, since the individual comets are so small and at such large distances, we have no direct evidence about the Oort Cloud. ... T he Kuiper Belt is a disk-shaped region past the orbit of Neptune roughly 30 to 100 AU from the Sun containing many small icy bodies. ... Small Bodies .. ...

Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

... Bad Astronomy . ... This page has images and links that George Noory and I discussed on the Coast to Coast AM radio show on Friday night, July 29, 2005. ... Two new objects were announced today, and both are big, maybe as big as Pluto. One is almost certainly bigger than Pluto! ... I've been saying for years that we will almost certainly find something bigger than Pluto out there in the dark, cold reaches of our solar system (I've said so on Coast to Coast several times, actually). ...

... Kuiper belt objects are icy bodies in the outer solar system. ... Views of Kuiper Belt Objects . Object 1993 SC . This image shows a small part of the discovery frames of 1993 SC, one of the brightest Kuiper-Belt objects so far discovered. ... Assuming that Object 1993 SC reflects light much like other primitive asteroids and comets in the out solar system, the diameter is around 300 kilometers (186 miles), or just a quarter the size of Pluto's moon Charon. ...
