1. Stars with Less Secure Periods
Next: Stars without Periods Up: Other Stars Previous: Stars with Highly . ... However, due to lower signal to noise their periods are less secure. ... This could be interpreted as a continuous distribution with statistically insignificant deviations which give the appearance of gaps or a real gap. ... When the distributions of periods greater five days are compared for the ONC stars and those near Orionis the KS test gives a 47% probability of these distributions being drawn from the same population. ...

2. The Spectral Energy Distribution of Dust Emission in the Edge-on Spiral Galaxy
We explore variations in dust emission within the edge-on Sd spiral galaxy NGC 4631 using 3.6-160 ЮМm Spitzer Space Telescope data and 450-850 ЮМm JCMT data with the goals of understanding the relation between PAHs and dust emission, studying the variations in the colors of the dust emission, and searching for possible excess submillimeter emission compared to what is expected from dust models extrapolated from far-infrared wavelengths. ...

7. Bias-Free Parameter Estimation with Few Counts, by Iterative Chi-Squared
... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

8. Low-Mass Star Formation
Next: Jets Up: M.D. Smith Previous: High-Mass Star Formation Contents . By contrast, stars of low mass like our Sun are formed within molecular clumps. Michael Smith has been investigating the clumps and the individual cores they contain within one nearby cloud near the star Rho Ophiuchi. With Stanke (Hawaii), Khanzadyan (Heidelberg) and Gredel (Calar Alto), he has determined the masses of over 100 protostellar cores and compared this to the distribution of masses for stars. ...

9. APOD: 2011 May 23 - An Unexpected Flare from the Crab Nebula
... 2011 May 23 . An Unexpected Flare from the Crab Nebula . ... As recently as one month ago, gamma-ray observations of the Crab Nebula by the Fermi Gamma Ray Space Telescope showed an unexpected increase in gamma-ray brightness, becoming about five times the nebula's usual gamma-ray brightness, and fading again in only a few days. ... The above image shows how the Crab Nebula normally appears in gamma rays, as compared to the Geminga pulsar, and how it then appeared during the recent brightening. ...

10. Description of algorithm
... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

15. Discussion and conclusions
... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...

Temperature flucuations . ... Most models of structure formation in the universe predict anisotropies in the CMBR. ... Therefore one must take into account not only the theoretically expected value of the temperature fluctuation but also the so-called cosmic variance, i.e. the theoretical error due to observing only one universe....
