... 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". ...

Within the Hubble Ultra Deep Field there are approximately 10,000 discrete objects. ... Most of these objects are very small and likely have masses in the range of 10 5 to 10 7 solar masses.

Next: Ejectors in Massive Binary Previous: Artificial Galaxy: Full Matrix . The first version of the Scenario Machine was aimed especially at the simulation of massive binary star evolution. ... First, there is a large class of intermediate mass binaries (say, consisting initially of 8 + 5 solar masses) that can also produce NS and thus lead to the formation of a bright X-ray source. ...

The black hole (BH) masses in the centers of active galactic nuclei (AGNs) have been estimated for a sample of radio-selected, flat-spectrum quasars to investigate the relationship between BH mass and radio properties of quasars. ... In contrast to previous studies, we find no correlation between BH mass and radio power in these AGNs. We find a range in BH mass similar to that seen in radio-quiet quasars from previous studies. ... You can now find me in room 99 at Epping. ...

... Not only can the Sun turn night to day, it can transform obscure 1950s jingles into 1990s alternative-rock hits. ... The sun is a mass of incandescent gas, . ... Studying the Sun can tie together subjects across the curriculum. ... Sunspots and prominences--the tongues of hot plasma which shoot off the Sun's surface and arch gracefully back, following the invisible tethers of magnetic field lines--are just two examples of solar volatility. ... The black dots will be easy to see. ...

In the Table below the masses of some asteroids which were determined during the last years are listed. ...

Galileo showed convincingly that heavy objects fell no faster that light ones. ... If an iron ball was pulled down with a much greater force than a wooden one of the same size, why didn't it fall any faster? ... 1) It is harder to lift. ... It is the fact that the loaded wagon has a greater mass that gives it a larger inertia , a larger tendency to oppose any change in its state of rest or of constant motion in a straight line. ... One important quantity was the body mass of the astronauts. ...

... 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. ...
