... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...

... Two new LBV stars have been discovered in the Andromeda Galaxy. ... In Figure 1 the spectral energy distributions for six stars are shown: upper row - the newly discovered LBV stars, middle row - two well-known LBV stars Var A-1 and AE And, the lower row - two new B[e]-supergiant stars in Andromeda. ... Infrared spectra of the stars in the Andromeda Galaxy: two classical LBVs Var A-1 and AE And, two new LBVs J004526.62 and J004051.59, and two new B[e]-supergiants J004417.10 and J004444.52. ...

... Astrophysics Group . ... Pulsars . ... Stars ? ... The array was designed to detect compact radio sources such as these by virtue of the fact that they would scintillate (twinkle) when observed from the Earth through the interplanetary medium ? ... One of Antony Hewish?s research students, Jocelyn Bell, was set the task of operating the telescope and inspecting the daily charts for the kind deflections in the trace which occurred when a scintillating source passed over the array. ...

Next: ANALYSE/ROMAFOT Up: The Interactive Path Previous: The Interactive Path . FIND/ROMAFOT frame [cat_tab] . This command works exactly like SELECT/ROMAFOT and therefore needs no detailed explanation. The only difference is that FIND/ROMAFOT , designed to select many stars, stores the positions of the objects in a catalogue table which has a different structure than then the intermediate table created by SELECT/ROMAFOT . This table serves as as input for the command ANALYSE/ROMAFOT . ...

Because the core API runs in a different thread to the main program, direct function calls to some classes can cause problems - especially when images must be loaded, or other non-atomic operations are involved. ... Connect signals from the StelMainScriptAPI to the instance of this class running in the main thread and let the slots do the work which is not possible within StelMainScriptAPI itself. ...

The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...
