  • Analysis of Eclipsing Binary Data
    analysis of eclipsing binary data A.E. Lynas-Gray and C. Causer October 2012 AS33 1 Introduction The purpose of this experiment is to verify physical and geometric characteristics of an eclipsing binary already published in the literature, using radial velocity and light curves provided. In carrying out the experiment, the most important thing is to appreciate how the masses, radii, shapes, temperatures and orbits of the two stars determine the observed light and radial velocity variations. The book by Hilditch (2001) is an excellent introduction to binary stars and is recommended reading. Once the period has been determined, masses, radii and effective temperatures of both components are estimated using a “back of an envelope” calculation; these results are then used as a starting ap- proximation in a light and radial velocity curve synthesis code. The idea is to reproduce observed light and radial velocity curves, but in practice “back of the envelope” results will need adjustment before a good agreement with observation is achieved. At the time of writing, only data for R Canis Majoris are provided. 2 Initial setup Begin by creating a xterm window in which commands can be typed. The window is created using the Mouse to click on the large “X” in the middle of the dock on the bottom of your screen. The large “X” may bob up and down a bit before the window appears. The steps detailed below provide the setup necessary for experiments carried out in the Astrophysics Laboratory. The .profile, .bashrc, .cups/lpoptions and .Xdefaults files in your home directory are changed as a result of carrying out steps listed below; if these files have been previously setup to carry out an experiment in another laboratory, please consult a demonstrator before proceeding.

  • PHOTOMETRIC and SPECTROSCOPIC STUDY of R Cma*
    PHOTOMETRIC AND SPECTROSCOPIC STUDY OF R CMa* K. R. RADHAKRISHNAN, M. B. K. SARMA, and K. D. ABHYANKAR Centre of Advances Study in Astronomy, Osmania University, Hyderabad, India (Received 19 July, 1983) Abstract. UBFlight curves and spectrograms of RCMa obtained with the 48-inch telescope of Japal- Rangapur Observatory during 1980-82 have been used for deriving the eclipse and orbital elements as well as the absolute dimensions of the components. The primary is found to be a Main-Sequence F2V star of mass 1.52 M and the secondary a subgiant star of spectral type G8 and mass 0.20 M which fills its Roche lobe, in agreement with Kopal and Shapley (1956) results, Kopal (1959), or Sahade's (1963) results. From a consideration of the possible evolution of this system it is concluded that a large fraction of the original mass of the secondary is lost from the system. A study of the period changes indicates the possible presence of a third component of mass of about 0.5 MQ which is most likely to be an M dwarf. 1. Introduction R Canis Majoris is the prototype of a group of Algol systems having very low mass function. It is known to exhibit peculiarities in its light curve that change from time to time and is thought to be surrounded by gas. It also shows changes in period which are not yet fully understood. Hence, this star was included in the photometric and spectroscopic observing programme of Japal-Rangapur Observatory. R CMa was observed photometrically with the 48-inch telescope in the standard UBV colors on 34 nights during 1980-82 covering nine minima.

C ARTER Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1995 NATIONAL ACADEMIES PRESS WASHINGTON D.C. SETH CARLO CHANDLER, JR. September 16, 1846–December 31, 1913 BY W. E. CARTER AND M. S. CARTER ETH CARLO CHANDLER, JR., IS best remembered for his re- Ssearch on the variation of latitude (i.e., the complex wobble of the Earth on its axis of rotation, now referred to as polar motion). His studies of the subject spanned nearly three decades. He published more than twenty-five techni- cal papers characterizing the many facets of the phenom- enon, including the two component 14-month (now referred to as the Chandler motion) and annual model most gener- ally accepted today, multiple frequency models, variation of the frequency of the 14-month component, ellipticity of the annual component, and secular motion of the pole. His interests were much wider than this single subject, however, and he made substantial contributions to such diverse areas of astronomy as cataloging and monitoring variable stars, the independent discovery of the nova T Coronae, improv- ing the estimate of the constant of aberration, and comput- ing the orbital parameters of minor planets and comets. His publications totaled more than 200. Chandler’s achievements were well recognized by his con- temporaries, as documented by the many prestigious awards he received: honorary doctor of law degree, DePauw Uni- versity; recipient of the Gold Medal and foreign associate of the Royal Astronomical Society of London; life member 45 46 BIOGRAPHICAL MEMOIRS of the Astronomische Gesellschaft; recipient of the Watson Medal and fellow, American Association for the Advance- ment of Science; and fellow, American Academy of Arts and Sciences.

    Paul Murrell A Data Viewer for R A Data Viewer for R Paul Murrell The University of Auckland July 30 2009 Paul Murrell A Data Viewer for R Overview Motivation: STATS 220 Problem statement: Students do not understand what they cannot see. What doesn’t work: View() A solution: The rdataviewer package and the tcltkViewer() function. What else?: Novel navigation interface, zooming, extensible for other data sources. Paul Murrell A Data Viewer for R STATS 220 Data Technologies HTML (and CSS), XML (and DTDs), SQL (and databases), and R (and regular expressions) Online text book that nobody reads Computer lab each week (worth 0.5%) + three Assignments 5 labs + one assignment on R Emphasis on creating and modifying data structures Attempt to use real data Paul Murrell A Data Viewer for R Example Lab Question Read the file lab10.txt into R as a character vector. You should end up with a symbol habitats that prints like this (this shows just the first 10 values; there are 192 values in total): > head(habitats, 10) [1] "upwd1201" "upwd0502" "upwd0702" [4] "upwd1002" "upwd1102" "upwd0203" [7] "upwd0503" "upwd0803" "upwd0104" [10] "upwd0704" Paul Murrell A Data Viewer for R The file lab10.txt upwd1201 upwd0502 upwd0702 upwd1002 upwd1102 upwd0203 upwd0503 upwd0803 upwd0104 upwd0704 upwd0804 upwd1204 upwd0805 upwd1005 upwd0106 dnwd1201 dnwd0502 dnwd0702 dnwd1002 dnwd1102 dnwd1202 dnwd0103 dnwd0203 dnwd0303 dnwd0403 dnwd0503 dnwd0803 dnwd0104 dnwd0704 dnwd0804 dnwd1204 dnwd0805 dnwd1005 dnwd0106 uppl0502 uppl0702 uppl1002 uppl1102 uppl0203 uppl0503

    }o PUBLICATIONS OF THE DAVID DUNLAP OBSERVATORY UNIVERSITY OF TORONTO Volume II Number 7 THE LUMINOSITY FUNCTIONS OF GALACTIC STAR CLUSTERS SIDNEY van den BERGH and DAVID SHER I960 TORONTO, CANADA THE LUMINOSITY FUNCTIONS OF GALACTIC STAR CLUSTERS Abstract The luminosity functions of the following galactic clusters have been obtained down to mpe ^ 20 NGC 188 NGC 663 NGC 2158 NGC 2539 XGC 436 NGC 1907 NGC 2194 NGC 2682 (M67) NGC 457 NGC 1960 (M36) NGC 2362 (r CMa) NGC 7789 NGC 559 NGC 2099 (M37) NGC 2477 IC 361 NGC 581 (M103) NGC 2141 NGC 2506 Trumpler 1 It is found that striking differences exist among the main sequence luminosity functions of individual clusters. Also it appears that the faint ends of the luminosity functions of galactic clusters differ systematically from the van Rhijn-Luyten lumi- nosity function for field stars in the vicinity of the sun in the sense that (with one exception) all the clusters which were investigated to faint enough limits, had luminosity functions which either decreased or remained constant below Mpg = 4-5. The differences between individual clusters and the differences between the lumi- nosity functions of clusters on the one hand and field stars on the other show that the luminosity function of star creation is not unique. This result is taken to indicate that the luminosity function with which stars are created probably depends on the physical conditions prevailing in the region of star creation. It is also shown that the observed surface density of cluster stars may be repre- sented by an exponentially decreasing function of the distance from the cluster centre.
