3. New LBV Star Discovered in the Galaxy
... Luminous blue variable (LBV) stars are the most massive stars with 40-120 solar masses, which are passing the short stage of evolution losing their hydrogen envelopes before exploding as Supernovae. These are extremely rare objects, only about a dozen of the most massive LBVs are known in the Galaxy. ... In the spectral observations of stars with infrared circular nebulae, found in the Spitzer survey (24 microns), a new LBV star in the Galaxy was discovered. It was named MN112. ...

... Астронет | ... Переменные Звезды | ... Микролинзирование . ... На протяжении последних нескольких лет в рамках проекта MACHO проводятся наблюдения микролинзирования звезд Большого Магелланова Облака - спутника нашей Галактики. Эффект микролинзирования заключается в гравитационной фокусировке света звезды массивным объектом, находящимся на луче зрения между звездой и наблюдателем. ... Согласно некоторым гипотезам, линзами могут являться реликтовые черные дыры или "нейтралинные звезды". ...

5. Very Low Mass PMS Objects
... Since the reddening found for the stars in Table 13 was small, no reddening correction was attempted. ... These diamonds indicate the positions of very low mass, 3 Myr old, objects from the work of Burrows et al. ... This optical V versus R - I scheme is a very powerful method of detecting very low mass (VLM) objects. ... Because of this, young brown dwarfs are intrinsically no more difficult to observe in the optical than low mass stars at the age of Orionis. ...

Discover the cosmos! ... 2005 July 31 . Solar System Object Larger than Pluto Discovered . ... A faint, slowly moving dot discovered by computer shows clear signs of being a deep Solar System object at least as large as Pluto . The object, designated 2003 UB 313 , is currently situated nearly 100 times the Earth-Sun distance -- over twice the average Pluto-Sun distance. ... Since 2003 UB 313 is surely not completely reflective , it could be substantially larger. ... About APOD | ...

10. ASP: A Good Definition of the Word "Planet": Mission Impossible?
... 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! . ...

13. Mass Feeding and Feedback in Young Stellar Objects
... 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. ...

Next: The Evolutionary Status of Up: No Title Previous: Massive X-ray Binaries . After 25 years of pulsar studies, a radiopulsar has been discovered in a binary system with a massive optical companion (Johnston et al. ... As shown in the very first calculations of joint evolution of NS and normal stars in binaries (Kornilov and Lipunov, 1983b[ 86 ]) a considerable fraction (maybe, the majority) of NS in binary systems having an optical companion must be at the ejector љ (E) state. ...

16. Summary of the present status of the survey
... Altogether among the objects of first priority in Papers I through IV, we discovered 321 new emission-line objects (20 of them QSOs), and for 55 known ELGs we got quantitative data for their emission lines. Preliminary classification of the 356 ELGs yields 275 ( 77 %) confident or probable blue compact/low-mass H II -galaxies. This large fraction demonstrates the high efficiency of this survey to find low-mass galaxies with H II -type spectra on the Hamburg Quasar Survey photoplates. ...
