... 172 ] Briefly, the count rate at the detector from a source at a redshift z is . ... Figure 55 shows the ``Green functions'' for the double compact binary merging rate   evolution assuming no collapse anisotropy. ... Another way that diverse peculiarities in the - distribution induced by the sources evolution could arise is connected with a possible non-monotonic character of the star formation rate in galaxies. ... 22 ] Figure  56 shows two-dimensional cuts through the parameter space. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... Australia Telescope Steering Committee . ... Parkes radio telescope . ... Late Stages of Stellar Evolution . Welcome to the home page of the Late Stages of Stellar Evolution" We are a research group which operates within the Astrophysics Group of the Australia Telescope National Facility. ... To investigate the late stages of stellar evolution and in particular the role of stellar mass-loss in the evolution of asymptotic giant branch stars, proto-planetary nebulae and extremely massive stars. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... Galaxy Evolution home . ... The origin and evolution of radio sources . Radio sources and their environments . ... We are investigating how this interaction effects galaxy evolution in general as well as the feedback effect of the radio source on its host galaxy and AGN. ... One direct observational manifestation of this interaction is the existence of extended regions of emission-line gas which show a clear spatial relationship to the radio source itself. ...

Chiaki Kobayashi, Ralph Sutherland How galaxies did form and evolution? - to answer this unsolved problem, we are simulating the formation and evolutionary history of galaxies in the Universe, including star formation, supernovae feedback, and chemical enrichment. Comparing the spacial distribution of elements within galaxies with observations, we will examine fundamental physical processes that drive galaxy formation. ...

... Baffled, you turn to the waiter. ... The waiter smiles. ... Some prefer small stars while others insist that the larger they are the better they are. ... Of course," he adds, sensing your concern, "you are the guest of Chez Stella. ... Immediately you hear the "tock... tock... tock" of the stopwatch, and you gaze deep into the distant star. ... You hadn't noticed before, but it is giving off vast symmetric clouds of what looks like smoke or dust hanging in the space around the beautiful star. ...

Although most white dwarfs do indeed fade away to become stellar cinders, gigantic crystals of carbon and oxygen, a few have just enough hydrogen and helium fuel left on their surface to be re-ignited. ...

The Moon was likely created from debris expelled when a Mars-sized object violently impacted the Earth about 4.5 billion years ago. ... Rocks large and small continued to impact the surface, including a particularly large impact that created Aitken Basin about 4.3 billion years ago. ... Over the next few billion years lava flowed into Earth-side basins , eventually cooling into the dark maria we see today. ...

... 601Artyukh A survey of compact ( q < 1") radio sources is being made with the Large Phased Array (LPA) of Lebedev Physical Institute. ... The survey of scintillating radio sources in two areas of 7C survey has enabled to detect 414 compact sources, 380 of them 92% were detect first. The scintillating source count (from observations of two areas) has confirmed the decrease
