The Search for Exomoons and the Characterization of Exoplanet Atmospheres
Corso di Laurea Specialistica in Astronomia e Astrofisica The search for exomoons and the characterization of exoplanet atmospheres Relatore interno : dott. Alessandro Melchiorri Relatore esterno : dott.ssa Giovanna Tinetti Candidato: Giammarco Campanella Anno Accademico 2008/2009 The search for exomoons and the characterization of exoplanet atmospheres Giammarco Campanella Dipartimento di Fisica Università degli studi di Roma “La Sapienza” Associate at Department of Physics & Astronomy University College London A thesis submitted for the MSc Degree in Astronomy and Astrophysics September 4th, 2009 Università degli Studi di Roma ―La Sapienza‖ Abstract THE SEARCH FOR EXOMOONS AND THE CHARACTERIZATION OF EXOPLANET ATMOSPHERES by Giammarco Campanella Since planets were first discovered outside our own Solar System in 1992 (around a pulsar) and in 1995 (around a main sequence star), extrasolar planet studies have become one of the most dynamic research fields in astronomy. Our knowledge of extrasolar planets has grown exponentially, from our understanding of their formation and evolution to the development of different methods to detect them. Now that more than 370 exoplanets have been discovered, focus has moved from finding planets to characterise these alien worlds. As well as detecting the atmospheres of these exoplanets, part of the characterisation process undoubtedly involves the search for extrasolar moons. The structure of the thesis is as follows. In Chapter 1 an historical background is provided and some general aspects about ongoing situation in the research field of extrasolar planets are shown. In Chapter 2, various detection techniques such as radial velocity, microlensing, astrometry, circumstellar disks, pulsar timing and magnetospheric emission are described. A special emphasis is given to the transit photometry technique and to the two already operational transit space missions, CoRoT and Kepler. -

T2 Tanker “Scotts Bluff”
National Park Service Scotts Bluff U.S. Department of the Interior Scotts Bluff National Monument Nebraska T2 Tanker “Scotts Bluff” T2 Tanker The S.S. Scotts Bluff T2-SE-A1 tanker was the 67th out of the 153 T2 tankers built at the Kaiser Com- Scotts Bluff pany’s Swan Island Shipyards in Portland, Oregon. The tanker was named after the historic Scotts Bluff National Monument, a landmark on the Oregon Trail. The Scotts Bluff was completed in June 1944 and launched on October 5,1944. At the time, the Scotts Bluff was built in a record of 39 days. T2-SE-A1 By the winter of 1940-1941, the Nazis controlled all of the coast of Europe. German aircraft and Tankers submarines seemed likely to strangle Britain by destroying its shipping. Though U.S. ships were for- bidden to enter the cambat area by the Neutrality Act of 1939, President Franklin Roosevelt wanted to aid Britain while simultaneously strengthening the defense of the Western Hemisphere. He an- nounced his intention to create an emergency shipbuilding program by building 200 standard-type cargo ships, later known as “Liberty Ships”. The T2 tanker, Scotts Bluff, was one of the 481 T2-SE-A1 tankers built at four different shipyards. The T2 tanker was an oil tanker constructed and produced in large number in the United States dur- ing World War II. These were the largest “Navy Oilers” at the time and were constructed between 1940 and 1945. During that time, the average production time from” laying of the keel” to “fitting out” was 70 days. -

(2) Commission Regulation (EC) No 748/2009 (3) establishes a list of aircraft operators which performed an aviation activity listed in Annex I to Directive 2003/87/EC on or after 1 January 2006. (3) That list aims to reduce the administrative burden on aircraft operators by providing information on which Member State will be regulating a particular aircraft operator. (4) The inclusion of an aircraft operator in the Union’s emissions trading scheme is dependent upon the performance of an aviation activity listed in Annex I to Directive 2003/87/EC and is not dependent on the inclusion in the list of aircraft operators established by the Commission on the basis of Article 18a(3) of that Directive. -

Stanek20 Draft version April 3, 2012 ABSTRACT The Panchromatic Hubble Andromeda Treasury (PHAT) is an on-going Hubble Space Telescope (HST) Multicycle Treasury program to image ∼1/3 of M31's star forming disk in six filters, spanning from the ultraviolet (UV) to the near-infrared (NIR). We use the Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) to resolve the galaxy into millions of individual stars with projected radii from 0{20 kpc. The full survey will cover a contiguous 0.5 square degree area in 828 orbits. Imaging is being obtained in the F275W and F336W filters on the WFC3/UVIS camera, F475W and F814W on ACS/WFC, and F110W and F160W on WFC3/IR. The resulting wavelength coverage gives excellent constraints on stellar temperature, bolometric luminosity, and extinction for most spectral types. The data produce photometry with a signal-to-noise ratio of 4 at mF275W = 25:1, mF336W = 24:9, mF475W = 27:9, mF814W = 27:1, mF110W = 25:5, and mF160W = 24:6 for single pointings in the uncrowded outer disk; in the inner disk, however, the optical and NIR data are crowding limited, and the deepest reliable magnitudes are up to 5 magnitudes brighter. -
