The Constellation Microscopium, the Microscope Microscopium Is A
The Constellation Microscopium, the Microscope Microscopium is a small constellation in the southern sky, defined in the 18th century by Nicolas Louis de Lacaille in 1751–52 . Its name is Latin for microscope; it was invented by Lacaille to commemorate the compound microscope, i.e. one that uses more than one lens. The first microscope was invented by the two brothers, Hans and Zacharius Jensen, Dutch spectacle makers of Holland in 1590, who were also involved in the invention of the telescope (see below). Lacaille first showed it on his map of 1756 under the name le Microscope but Latinized this to Microscopium on the second edition published in 1763. He described it as consisting of "a tube above a square box". It contains sixty-nine stars, varying in magnitude from 4.8 to 7, the lucida being Gamma Microscopii of apparent magnitude 4.68. Two star systems have been found to have planets, while another has a debris disk. The stars that now comprise Microscopium may formerly have belonged to the hind feet of Sagittarius. However, this is uncertain as, while its stars seem to be referred to by Al-Sufi as having been seen by Ptolemy, Al-Sufi does not specify their exact positions. Microscopium is bordered Capricornus to the north, Piscis Austrinus and Grus to the west, Sagittarius to the east, Indus to the south, and touching on Telescopium to the southeast. The recommended three-letter abbreviation for the constellation, as adopted Seen in the 1824 star chart set Urania's Mirror (lower left) by the International Astronomical Union in 1922, is 'Mic'. -

DARK GREEN COLOR INDEX AS A METHOD OF REAL-TIME IN-SEASON CORN NITROGEN MEASUREMENT AND FERTILIZATION DARK GREEN COLOR INDEX AS A METHOD OF REAL-TIME IN-SEASON CORN NITROGEN MEASUREMENT AND FERTILIZATION A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Crop, Soil, and Environmental Science By Upton Gardner Siddons Hendrix College Bachelor of Arts in Environmental Studies, 2007 May 2013 University of Arkansas ABSTRACT Corn ( Zea mays L.) requires higher rates of nitrogen fertilizer than any other major U.S. crop. Soil and applied N are subject to loss through various mechanisms. A timely, accurate, and precise method for measuring in-season corn N status is needed to ensure high yield and to allow producers to increase nitrogen use efficiency. -

The Hertzsprung - Russell Diagram Today You Will Be Making the Hertzsprung - Russell Diagram
Name: ___________________________________ The Hertzsprung - Russell diagram Today you will be making the Hertzsprung - Russell diagram. The H-R diagram allows astronomers to classify stars into groups. The two axes for this graph will be temperature and magnitude. When we refer to temperature, we are talking about the surface of the star. The surface temperature is much cooler. For example, our sun’s surface temperature is ~5,500K to 6,000 K. Kelvin is a temperature scale very similar to Celsius. Absolute magnitude is a measurement of how bright a star really is. This is determined by its size and by its temperature. Even though it might look bright in our sky, we try to compare all stars as if we were standing the exact same distance away from each one. This magnitude value is stated by calculating how bright the object would shine at a fixed distance away in space, ~32.6 light years (10 parsecs for those wanting another measurement to think about).

We performed deep optical observations of the field of an old, fast-moving radio pulsar PSR B1133+16 in an attempt to detect its optical counterpart and a bow shock nebula. Methods. The observations were carried out using the direct imaging mode of FORS1 at the ESO VLT/UT1 telescope in the B, R,and Hα bands. We also used archival images of the same field obtained with the VLT in the B band and with the Chandra/ACIS in X-rays. Results. In the B band we detected a faint (B = 28m. 1 ± 0m. 3) source that may be the optical counterpart of PSR B1133+16, as it is positionally consistent with the radio pulsar and with the X-ray counterpart candidate published earlier. -
The Fundamentals of Stargazing Sky Tours South
The Fundamentals of Stargazing Sky Tours South 01 – The March Sky Copyright © 2014-2016 Mintaka Publishing Inc. www.CosmicPursuits.com -2- The Constellation Orion Let’s begin the tours of the deep-southern sky with the most famous and unmistakable constellation in the heavens, Orion, which will serve as a guide for other bright constellations in the southern late-summer sky. Head outdoors around 8 or 9 p.m. on an evening in early March, and turn towards the north. If you can’t find north, you can ask someone else, or get a small inexpensive compass, or use the GPS in your smartphone or tablet. But you need to face at least generally northward before you can proceed. You will also need a good unobstructed view of the sky in the north, so you may need to get away from structures and trees and so on. The bright stars of the constellation Orion (in this map, south is up and east is to the right) And bring a pair of binoculars if you have them, though they are not necessary for this tour. Fundamentals of Stargazing -3- Now that you’re facing north with a good view of a clear sky, make a 1/8th of a turn to your left. Now you are facing northwest, more or less. Turn your gaze upward about halfway to the point directly overhead. Look for three bright stars in a tidy line. They span a patch of sky about as wide as your three middle fingers held at arm’s length. This is the “belt” of the constellation Orion. -
Where Are All the Sirius-Like Binary Systems?
Mon. Not. R. Astron. Soc. 000, 1-22 (2013) Printed 20/08/2013 (MAB WORD template V1.0) Where are all the Sirius-Like Binary Systems? 1* 2 3 4 4 J. B. Holberg , T. D. Oswalt , E. M. Sion , M. A. Barstow and M. R. Burleigh ¹ Lunar and Planetary Laboratory, Sonnett Space Sciences Bld., University of Arizona, Tucson, AZ 85721, USA 2 Florida Institute of Technology, Melbourne, FL. 32091, USA 3 Department of Astronomy and Astrophysics, Villanova University, 800 Lancaster Ave. Villanova University, Villanova, PA, 19085, USA 4 Department of Physics and Astronomy, University of Leicester, University Road, Leicester LE1 7RH, UK 1st September 2011 ABSTRACT Approximately 70% of the nearby white dwarfs appear to be single stars, with the remainder being members of binary or multiple star systems. The most numerous and most easily identifiable systems are those in which the main sequence companion is an M star, since even if the systems are unresolved the white dwarf either dominates or is at least competitive with the luminosity of the companion at optical wavelengths. Harder to identify are systems where the non-degenerate component has a spectral type earlier than M0 and the white dwarf becomes the less luminous component. Taking Sirius as the prototype, these latter systems are referred to here as ‘Sirius-Like’. There are currently 98 known Sirius-Like systems. Studies of the local white dwarf population within 20 pc indicate that approximately 8 per cent of all white dwarfs are members of Sirius-Like systems, yet beyond 20 pc the frequency of known Sirius-Like systems declines to between 1 and 2 per cent, indicating that many more of these systems remain to be found.
