On leaving the planetarium, turn around and look northwards over the roof of the building. To your right is a group of stars like the outline of a saucepan standing up on it’s handle. This is the Plough (also called the Big Dipper) and is part of the constellation Ursa Major, the Great Bear. The top two stars are called the Pointers. Check with binoculars. Not all stars are white. The colour shows that Dubhe is cooler than Merak in the same way that red-hot is cooler than white-hot. 2. Use the Pointers to guide you to the left, to the next bright star. This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris.

Engagement Ring The Engagement Ring: Through binoculars, the North Star (Polaris) seems to be the brightest on a small ring of stars. Not a constellation or cluster, this asterism looks like a diamond engagement ring on which Polaris shines brightly as the diamond. Big Dipper The Big Dipper (also known as the Plough) is an asterism consisting of the seven brightest stars of the constellation Ursa Major. Four define a "bowl" or "body" and three define a "handle" or "head". It is recognized as a distinct grouping in many cultures. The North Star (Polaris), the current northern pole star and the tip of the handle of the Little Dipper, can be located by extending an imaginary line from Big Dipper star Merak (β) through Dubhe (α). This makes it useful in celestial navigation. Little Dipper Constellation Ursa Minor is colloquially known in the US as the Little Dipper, because its seven brightest stars seem to form the shape of a dipper (ladle or scoop). The star at the end of the dipper handle is Polaris, the North Star. Polaris can also be found by following a line through two stars in Ursa Major—Alpha and Beta Ursae Majoris—that form the end of the 'bowl' of the Big Dipper, for 30 degrees (three upright fists at arms' length) across the night sky. Boötes Boötes has a funny name.

  • Cyclic-Permutation Invariant Networks for Modeling Periodic Sequential Data: Application to Variable Star Classification
    Cyclic-Permutation Invariant Networks for Modeling Periodic Sequential Data: Application to Variable Star Classification Keming Zhang∗ Joshua S. Bloom Department of Astronomy Department of Astronomy University of California at Berkeley University of California at Berkeley Berkeley, CA 94720 Berkeley, CA 94720 [email protected] [email protected] Abstract Current recurrent and convolutional neural network (RNN; CNN) architectures are sub-optimal for modeling periodic sequences because of their acyclic topology. Here, we present cyclic-permutation invariant networks, a new type of CNN for which the invariance to cyclic-permutations, or phase shifts, is guaranteed by representing data in phase-space and performing convolutions in polar coordinates, which we implement by means of “Symmetry Padding.” Across three different datasets of periodic variable star light-curves (time-series of brightness) [1, 2, 3], we show that two particular implementations of the cyclic-permutation invariant network: the iTCN and the iResNet, consistently outperform both non-invariant versions of the same network, as well as previous state-of-the-art approaches including Random Forests. This methodology is first presented in [4] and is applicable to a wide range of science domains where periodic data abounds due to physical symmetries. 1 Introduction Strictly periodic data is common in the physical sciences where periodicity occurs both spatially and temporally. Neural networks for which invariances arising from periodicity are explicitly considered either in the input features or the loss function, have been previously applied to particle physics [5] and atomic physics/chemistry [6]. In this study, we focus on periodic time series arising from variable stars, which is important to many sub-fields of astronomy, including the study of the cosmic distance ladder, galactic archaeology, and stellar evolution.

  • Extrasolar Planets and Their Host Stars
    Kaspar von Braun & Tabetha S. Boyajian Extrasolar Planets and Their Host Stars July 25, 2017 arXiv:1707.07405v1 [astro-ph.EP] 24 Jul 2017 Springer Preface In astronomy or indeed any collaborative environment, it pays to figure out with whom one can work well. From existing projects or simply conversations, research ideas appear, are developed, take shape, sometimes take a detour into some un- expected directions, often need to be refocused, are sometimes divided up and/or distributed among collaborators, and are (hopefully) published. After a number of these cycles repeat, something bigger may be born, all of which one then tries to simultaneously fit into one’s head for what feels like a challenging amount of time. That was certainly the case a long time ago when writing a PhD dissertation. Since then, there have been postdoctoral fellowships and appointments, permanent and adjunct positions, and former, current, and future collaborators. And yet, con- versations spawn research ideas, which take many different turns and may divide up into a multitude of approaches or related or perhaps unrelated subjects. Again, one had better figure out with whom one likes to work. And again, in the process of writing this Brief, one needs create something bigger by focusing the relevant pieces of work into one (hopefully) coherent manuscript. It is an honor, a privi- lege, an amazing experience, and simply a lot of fun to be and have been working with all the people who have had an influence on our work and thereby on this book. To quote the late and great Jim Croce: ”If you dig it, do it.
