In the collision, the stars mostly did not interact, but the gases and other matter were significantly altered. It is one of the heaviest stellar black holes so far known in the Milky Way and has a self-regulating black hole. One of 88 recognized regions of the celestial sphere in which the object appears. One of the nearest and brightest galaxies containing a supermassive black hole. is not spherical, rather it is egg shaped due to the non-radial nature of its pulsations. M81, also known as "Bode's Galaxy", is a large spiral galaxy. It is 22 times the diameter of our galaxy, and its starburst activity suggests that the galaxy is still growing larger. SNR G1.9+0.3 was most likely a double degenerate progenitor supernova. It is highly visible in the gamma-ray spectrum. Delta Cep is located in a binary system, and is one of the closest Cepheid variable stars, with only Polaris being closer. The intergalactic gas in the Abell 3627 is 180 million degrees Fahrenheit which causes star formation in the tails. V1647 Ori is a FU Orionis variable star, a low-mass protostar still partly surrounded by its birth cloud. It has one of the highest star formation rates of any galaxy. Anstelle des Regiowettbewerbes in Zürich (Schule Untermoos, Altstetterstrasse 248, 8048 Zürich). This page was last edited on 27 September 2020, at 16:47. GRS 1915+105 is an x-ray binary star system containing a regular star and a black hole. It uses X-Ray luminosity of galaxy clusters to calculate expansion speeds across the sky. Right ascension – analogous to longitude – is one component of an object's position. The. A Type 1a supernova remnant that was observed in 1572 and later studied by Tycho Brahe. The explosion occurred 400 years ago for Earth observers. Brown Dwarfs, Red Giants, White Dwarfs, Cepheid Variables, Supernova remnants, Globular Clusters). It has an appearance similar to a rose, hence its name. Along with 3C 48, it was the first object to be identified as what we now know to be quasars. It is the first evidence in X-rays of a supernova shock wave breaking through a cocoon of gas around the star. Youngest known planetary nebula; Radius 0.02 pc (as large as 130 solar systems), separated by 0.3arcsec; Age 2650 yr, gases light up for no more than 40 yr; Core mass 0.59 M_sun; ionized mass (nebula mass) 0.2Msol; Star at the center was originally a asymptotic giant branch B1 supergiant, still evolving to WD; White dwarf has strong hydrogen rich Balmer lines; Luminosity 3000 L_sun. It is considered an accurate representation of the formation of the Milky Way. It is one of the best examples of evidence for the existence of dark matter. JKCS 041. A Type 1a supernova remnant that burst in early November 1572 and was later studied by Tycho Brahe. NGC 1846 is a globular cluster with an unusual HR diagram: there are two turn-off points. Koekemoer et al. Often classified as U Geminorum type dwarf nova. Log in Sign up. A recurrent nova with a very massive white dwarf and a red dwarf-type star cooler than our sun. The rotation of the image on the sky with respect to the north pole of the celestial sphere. Abell 30 is a planetary nebula in a special, rarely-seen phase of evolution. science.olympiad.ch University of Bern, Hochschulstrasse 6, 3012 Bern +41 31 631 39 86. Optical double. One part is a white giant, and the other appears to be a star shrouded by a dark cloud of dust. Ruhig und routiniert beginnt das Olympiaden-Jahr 19/20. It contains "the Elephant's Trunk", a dark, dense globule in the nebula. RCW 103 is a supernova remnant containing the neutron star 1E 161348-5055 at its center. T Pyxidis is a recurrent nova and nova remnant containing a sun-like star and a white dwarf. Categorize the DSOs by their types or stages in stellar evolution (e.g. Here, you win friends, prizes and medals. For example - a Type Ia Supernova can either be the result of collision of two white dwarfs or accretion of matter from a stellar companion (often reaching the Red Giant stage), and its mostly uniform brightness can help astronomers determine distance to distant galaxies using the distance modulus. The camera filters that were used in the science observations. The X-ray jets of Centaurus A are thousands of light-years long, while the radio jets are over a million light-years long. Neutron star orbiting a conventional super-massive star. NGC 6888, also known as the Crescent Nebula, was created the powerful winds coming off of the Star WR 136, or HD 192163. Epsilon Aurigae is an eclipsing binary. SNR 0509-67.5 is a Type 1a supernova remnant found in the Large Magellanic Cloud. Enden tut es analog und goldig – mit der Abschlussfeier, dem Science Olympiad Day am 26. The closest known supernova remnant to us with a notable pulsar and neighboring nebulae. This has led to hypotheses that BP Psc has recently consumed a companion star or a large, gaseous planet.
