Astronomy 113 Laboratory Manual
UNIVERSITY OF WISCONSIN - MADISON Department of Astronomy Astronomy 113 Laboratory Manual Fall 2011 Professor: Snezana Stanimirovic 4514 Sterling Hall [email protected] TA: Natalie Gosnell 6283B Chamberlin Hall [email protected] 1 2 Contents Introduction 1 Celestial Rhythms: An Introduction to the Sky 2 The Moons of Jupiter 3 Telescopes 4 The Distances to the Stars 5 The Sun 6 Spectral Classification 7 The Universe circa 1900 8 The Expansion of the Universe 3 ASTRONOMY 113 Laboratory Introduction Astronomy 113 is a hands-on tour of the visible universe through computer simulated and experimental exploration. During the 14 lab sessions, we will encounter objects located in our own solar system, stars filling the Milky Way, and objects located much further away in the far reaches of space. Astronomy is an observational science, as opposed to most of the rest of physics, which is experimental in nature. Astronomers cannot create a star in the lab and study it, walk around it, change it, or explode it. Astronomers can only observe the sky as it is, and from their observations deduce models of the universe and its contents. They cannot ever repeat the same experiment twice with exactly the same parameters and conditions. Remember this as the universe is laid out before you in Astronomy 113 – the story always begins with only points of light in the sky. From this perspective, our understanding of the universe is truly one of the greatest intellectual challenges and achievements of mankind. The exploration of the universe is also a lot of fun, an experience that is largely missed sitting in a lecture hall or doing homework. -

Astronomy Observation Log Of
Astronomy Observation Log of: _________________________________ Your name here Keeping a log will teach you patience in observing. By accurately recording your observations, you will be spending more identifying faint details that you would otherwise miss with casual observing. As an added benefit, you’ll find that your observational skills will improve. Over time, you’ll train your eye to see more detail, and fainter objects that you may have not seen before. What once was only visible with averted vision, you may find you can see directly. Sketching your observations will hone you astronomy viewing and navigation skills. Seeing and Transparency Scales, Magnitude and Brightness Scale, Filters for Visual Observation (http://www.astromax.org/faq/aa01faq14.htm) Use the following scales for astronomical seeing and transparency when filling out your observing logs. ASTRONOMICAL SEEING LEVEL 1 - Severely disturbed skies: Even low power* views are uselessly shaky. Go read a good book. LEVEL 2 - Poor seeing: Low power images are pretty steady, but medium powers are not. LEVEL 3 - Good seeing: You can use about half the useful magnification of your scope. High powers* produce fidgety planets. LEVEL 4 - Excellent seeing: Medium-powers are crisp and stable. High-powers are good, but a little soft. LEVEL 5 - Superb seeing: Any power eyepiece produces a good crisp image. * The PRACTICAL LOWEST power magnification for any telescope is approximately 7 times for each inch of aperture. Example: 28X for a 4-inch (100mm) diameter telescope. * 'The PRACTICAL HIGHEST power magnification for any telescope is approximately 50 times for each inch of aperture. Example: 200X for a 4-inch (100mm) diameter telescope. -
Measuring Atmospheric Seeing with Khz SLR Georg Kirchner1, Daniel Kucharski2, Franz Koidl1, Jörg Weingrill1 1
Measuring Atmospheric Seeing with kHz SLR Georg Kirchner1, Daniel Kucharski2, Franz Koidl1, Jörg Weingrill1 1. Austrian Academy of Sciences, Institute for Space Research, Graz 2. Space Research Centre, Polish Academy of Sciences, Borowiec, Poland Contact: [email protected] ; [email protected] ; [email protected] ; [email protected] Abstract During night-time kHz SLR operation in Graz, we use an ISIT camera to see satellites, stars, and also the backscatter of the transmitted kHz laser beam (Fig. 1). This backscatter image of the laser beam shows a beam pointing jitter in the order of several arcseconds, caused by the actual atmospheric conditions (“Seeing”). Using real time image processing, we determine the area of this beam pointing jitter, and derive the actual astronomical seeing values. These values depend not only – as usual for optical astronomy - on actual atmospheric conditions and on elevation of telescope, but also on the angular speed of telescope motion. In addition, the seeing values are considerably bigger (worse) during winter time, when – due to heating and poor isolation of the Graz observatory - the air above the observatory roof is significantly more turbulent than during the other seasons. This beam pointing jitter due to atmospheric turbulence can reach a similar magnitude as the laser beam divergence; it spoils our pointing accuracy, affecting our return rate especially from higher satellites. To reduce these effects, we are planning to use a fast steering mirror, which is controlled by the ISIT image derived laser beam pointing offsets. Introduction The ISIT camera observes the backscatter of the transmitted laser beam; the image is transferred into the PC via a standard frame grabber. -
Measurements of Optical Turbulence on the Antarctic Plateau and Their Impact on Astronomical Observations
Measurements of Optical Turbulence on the Antarctic Plateau and their Impact on Astronomical Observations. Tony Travouillon Submitted in total ful¯lment of the requirements of the degree of Doctor of Philosophy School of Physics University of New South Wales September 2004 Abstract Atmospheric turbulence results taken on the Antarctic plateau are presented in this thesis. Covering two high sites: South Pole and Dome C, this work describes their seeing and meteorological conditions. Using an acoustic sounder to study the turbulence pro¯le of the ¯rst kilo- metre of the atmosphere and a Di®erential Image Motion Monitor (DIMM) to investigate the integrated seeing we are able to deduce important at- mospheric parameters such as the Fried parameter (r0) and the isoplanatic angle (θ0). It was found that at the two sites, the free atmosphere (above the ¯rst kilometer) was extremely stable and contributed between 0.200 and 0.300 of the total seeing with no evidence of jet or vortex peaks of strong turbulence. The boundary layer turbulence is what di®erentiates the two sites. Located on the Western flank of the plateau, the South Pole is prone to katabatic winds. Dome C on the other hand is on a local maximum of the plateau and the wind conditions are amongst the calmest in the world. Also linked to the topography is the vertical extent of the temperature in- version that is required to create optical turbulence. At the South Pole the inversion reaches 300 m and only 30 m at Dome C. This di®erence results in relatively poor seeing conditions at the South Pole ('1.800) and excellent at Dome C (0.2700). -

Indigenous Use of Stellar Scintillation to Predict Weather and Seasonal Change
Preprint – Proceedings of the Royal Society of Victoria Indigenous use of stellar scintillation to predict weather and seasonal change Duane W. Hamacher 1,2, John Barsa 3, Segar Passi 3, and Alo Tapim 3 1 Monash Indigenous Studies Centre, Monash University, Clayton VIC 3800, Australia 2 Mount Burnett Observatory, 420 Paternoster Rd, Mount Burnett VIC 3781, Australia 3 Meriam Elder, Murray Island, QLD, 4875, Australia Corresponding Author Email: [email protected] Abstract Indigenous peoples across the world observe the motions and positions of stars to de- velop seasonal calendars. Additionally, changing properties of stars, such as their brightness and colour, are also used for predicting weather. Combining archival stud- ies with ethnographic fieldwork in Australia’s Torres Strait, we explore the various ways Indigenous peoples utilise stellar scintillation (twinkling) as an indicator for predicting weather and seasonal change, discussing the scientific underpinnings of this knowledge. By observing subtle changes in the ways the stars twinkle, Meriam people gauge changing trade winds, approaching wet weather, and temperature changes. We then explore how the Northern Dene of Arctic North America utilise stellar scintillation to forecast weather. Keywords Cultural Astronomy; Ethnoastronomy; Indigenous Knowledge; Stellar Scintillation; Torres Strait Islanders 1 Introduction To the general public, the twinkling of stars serves as inspiration for art and poetry. While many Indigenous cultures draw their own poetic and aesthetic inspiration from this phenomenon, current ethnographic fieldwork shows that the twinkling of stars serves an important practical purpose to Indigenous peoples. A person’s ability to ac- curately “read” the various changes in the properties of stars can assist them in pre- dicting weather and seasonal change. -

Printed in U.S.A. .3 . 91ApJ. 19 THE IMAGING PERFORMANCE OF THE HUBBLE SPACE TELESCOPE Christopher J. Burrows,1,2 Jon A. Holtzman,3-4 S. M. Faber,3,5 Pierre Y. Bely,1,2 Hashima Hasan,1 C. R. Lynds,3,6 and Daniel Schroeder7 Received 1990 October 17; accepted 1990 December 7 ABSTRACT The Hubble Space Telescope suffers from significant spherical aberration and does not give the predicted diffraction-limited images. A maximum of about 16% of the light from a point source is concentrated in a O'.T radius, where 70% was expected. The images consist of this core, surrounded by a complex 4'.'0 diameter inner halo that contains most of the light and is caused by portions of the primary mirror that are not focusing correctly. Ground test results uncovered by the Allen Commission agree with results derived from studies of the on-orbit imagery. The pointing performance is also degraded, with guide stars for fine lock presently limited to 13.5 mag, compared to an expected limit of 14.5 mag. Some areas of the sky are therefore not accessible in fine lock. In addition, the spacecraft undergoes severe pointing disturbances during portions of the orbit, caused by thermal shocks. Nevertheless, HST represents a unique resource for high-resolution imaging of low-contrast bright objects through deconvolution techniques. Such techniques rely on the detailed information about the PSF that is given here. HST can split higher contrast fields into components when photometric accuracy is not important.
