Charles Street, Baltimore, MD 21212, USA ABSTRACT A non-redundant pupil mask placed in front of a low-resolution integral field spectrograph (IFS) adds a spectral dimension to high angular resolution imaging behind adaptive optics systems. We demonstrate the first appli- cation of this technique, using the spectroscopic binary star system β CrB as our target. The mask and IFS combination enabled us to measure the first low-resolution spectrum of the F3–F5 dwarf secondary component of β CrB, at an angular separation 141 mas from its A5–A7Vp primary star. To record multi-wavelength closure phases, we collected interferograms simultaneously in 23 spectral channels spanning the J and H bands (1.1 µm–1.8 µm), using the Project 1640 IFS behind the 249-channel PalAO adaptive optics system on the Hale telescope at Palomar Observatory. -

Summer Constellations
Night Sky 101: Summer Constellations The Summer Triangle Photo Credit: Smoky Mountain Astronomical Society The Summer Triangle is made up of three bright stars—Altair, in the constellation Aquila (the eagle), Deneb in Cygnus (the swan), and Vega Lyra (the lyre, or harp). Also called “The Northern Cross” or “The Backbone of the Milky Way,” Cygnus is a horizontal cross of five bright stars. In very dark skies, Cygnus helps viewers find the Milky Way. Albireo, the last star in Cygnus’s tail, is actually made up of two stars (a binary star). The separate stars can be seen with a 30 power telescope. The Ring Nebula, part of the constellation Lyra, can also be seen with this magnification. In Japanese mythology, Vega, the celestial princess and goddess, fell in love Altair. Her father did not approve of Altair, since he was a mortal. They were forbidden from seeing each other. The two lovers were placed in the sky, where they were separated by the Celestial River, repre- sented by the Milky Way. According to the legend, once a year, a bridge of magpies form, rep- resented by Cygnus, to reunite the lovers. Photo credit: Unknown Scorpius Also called Scorpio, Scorpius is one of the 12 Zodiac constellations, which are used in reading horoscopes. Scorpius represents those born during October 23 to November 21. Scorpio is easy to spot in the summer sky. It is made up of a long string bright stars, which are visible in most lights, especially Antares, because of its distinctly red color. Antares is about 850 times bigger than our sun and is a red giant. -

CONSTELLATION VULPECULA, the (LITTLE) FOX Vulpecula Is a Faint Constellation in the Northern Sky
CONSTELLATION VULPECULA, THE (LITTLE) FOX Vulpecula is a faint constellation in the northern sky. Its name is Latin for "little fox", although it is commonly known simply as the fox. It was identified in the seventeenth century, and is located in the middle of the northern Summer Triangle (an asterism consisting of the bright stars Deneb in Cygnus (the Swan), Vega in Lyra (the Lyre) and Altair in Aquila (the Eagle). Vulpecula was introduced by the Polish astronomer Johannes Hevelius in the late 17th century. It is not associated with any figure in mythology. Hevelius originally named the constellation Vulpecula cum ansere, or Vulpecula et Anser, which means the little fox with the goose. The constellation was depicted as a fox holding a goose in its jaws. The stars were later separated to form two constellations, Anser and Vulpecula, and then merged back together into the present-day Vulpecula constellation. The goose was left out of the constellation’s name, but instead the brightest star, Alpha Vulpeculae, carries the name Anser. It is one of the seven constellations created by Hevelius. The fox and the goose shown as ‘Vulpec. & Anser’ on the Atlas Coelestis of John Flamsteed (1729). The Fox and Goose is a traditional pub name in Britain. STARS There are no stars brighter than 4th magnitude in this constellation. The brightest star is: Alpha Vulpeculae, a magnitude 4.44m red giant at a distance of 297 light-years. The star is an optical binary (separation of 413.7") that can be split using binoculars. The star also carries the traditional name Anser, which refers to the goose the little fox holds in its jaws. -

Lesson Plan Earth’S Moon Milky Way Galaxy Planet Astronomy Satellite Star Earth Cycle Astrology Moon Sun Gravity Lunar Cycle Solar Energy Orbit Solar System
Astronomy (Part I) Stars and Solar Systems SDH 2017 OVERVIEW: Always fascinating, always perplexing, and truly overwhelming, the night sky offers endless discoveries to those wanting to learn and explore. Students will discover the evening sky by gazing through our telescope and learn more about the systems that organize our solar system and beyond! OBJECTIVES: Students will be able to: Identify the characteristics of stars in the sky. Summarize the size and scope of Earth in the solar system and the universe. Describe the relationship between our planet and the solar system. VOCABULARY: Stars Planets General Lesson Plan Earth’s Moon Milky Way Galaxy Planet Astronomy Satellite Star Earth Cycle Astrology Moon Sun Gravity Lunar Cycle Solar Energy Orbit Solar System NEXT GENERATION SCIENCE STANDARDS: Solar energy reaches the Earth through radiation, mostly in the form of visible light. (6.4.b) The sun is a star that appears larger and brighter than other stars because it is closer. Stars range greatly in their distance from Earth. (5-ESS1-1 and ESS1.A) The orbits of earth around the sun and of the moon around Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns. (5-ESS1-2 and Ess1.B) Materials: Binoculars/Celestrons or Star Gazers Flashlight Procedures: 1. Introduction: Astronomy vs. Astrology? A. Have students form a circle. Then have them turn around to stare up at the stars while remaining silent. Have them observe the night sky and discuss with them what they saw. Is it different compared to what they may see back home. -
