  • Neutron Stars

    Neutron Stars

    Chandra X-Ray Observatory X-Ray Astronomy Field Guide Neutron Stars Ordinary matter, or the stuff we and everything around us is made of, consists largely of empty space. Even a rock is mostly empty space. This is because matter is made of atoms. An atom is a cloud of electrons orbiting around a nucleus composed of protons and neutrons. The nucleus contains more than 99.9 percent of the mass of an atom, yet it has a diameter of only 1/100,000 that of the electron cloud. The electrons themselves take up little space, but the pattern of their orbit defines the size of the atom, which is therefore 99.9999999999999% Chandra Image of Vela Pulsar open space! (NASA/PSU/G.Pavlov et al. What we perceive as painfully solid when we bump against a rock is really a hurly-burly of electrons moving through empty space so fast that we can't see—or feel—the emptiness. What would matter look like if it weren't empty, if we could crush the electron cloud down to the size of the nucleus? Suppose we could generate a force strong enough to crush all the emptiness out of a rock roughly the size of a football stadium. The rock would be squeezed down to the size of a grain of sand and would still weigh 4 million tons! Such extreme forces occur in nature when the central part of a massive star collapses to form a neutron star. The atoms are crushed completely, and the electrons are jammed inside the protons to form a star composed almost entirely of neutrons.

    Figure 3: The normalised spectral energy distribution of 3 galaxies. From left to right we show a regular Ly-break galaxy (Fig. 2c), the “spiral” galaxy (Fig. 2d), and the very red galaxy from Figure 2e. The red continuum feature of the last two galaxies can be due to the Balmer/4000 Angstrom break or due to dust. Only one of these would be selected by the regular Ly-break selection technique, as the others are too faint in the optical (rest-frame UV). Acknowledgement References van Dokkum, P.

Its main objective is pixel basis in order to manually correct glitches consist of regions of high and low photon counts, and therefore, only parts of them suffer to perform an all-sky survey with better spatial resolution and that would have been missed in the pipeline from the slow transient response effect. Hence, we needed to devise a specific method to wider wavelength coverage than IRAS (first US, UK, Dutch process. These corrections include: (1) eliminate address the detector response as a whole. This method uses a contour aperture to include infrared satellite launched in 1983), mapping the entire sky in bad on-sky calibration sequences, (2) flag out both the faint and bright emission by setting a threshold of background + 3#.! six infrared bands.

    Structural Analysis of the Sextans Dwarf Spheroidal Galaxy

    MNRAS 000,1{16 (2015) Preprint 9 October 2018 Compiled using MNRAS LATEX style file v3.0 Structural analysis of the Sextans dwarf spheroidal galaxy T. A. Roderick,1? H. Jerjen,1 G. S. Da Costa,1 A. D. Mackey1 1Research School of Astronomy and Astrophysics, Australian National University, Canberra, ACT 2611, Australia Accepted XXX. Received YYY; in original form ZZZ ABSTRACT We present wide-field g and i band stellar photometry of the Sextans dwarf spheroidal galaxy and its surrounding area out to four times its half-light radius (rh = 695 pc), based on images obtained with the Dark Energy Camera at the 4-m Blanco tele- scope at CTIO. We find clear evidence of stellar substructure associated with the galaxy, extending to a distance of 820 (2 kpc) from its centre. We perform a sta- tistical analysis of the over-densities and find three distinct features, as well as an extended halo-like structure, to be significant at the 99:7% confidence level or higher. Unlike the extremely elongated and extended substructures surrounding the Hercules dwarf spheroidal galaxy, the over-densities seen around Sextans are distributed evenly about its centre, and do not appear to form noticeable tidal tails. Fitting a King 0 0 model to the radial distribution of Sextans stars yields a tidal radius rt = 83:2 ± 7:1 (2.08±0.18 kpc), which implies the majority of detected substructure is gravitationally bound to the galaxy. This finding suggests that Sextans is not undergoing significant tidal disruption from the Milky Way, supporting the scenario in which the orbit of Sextans has a low eccentricity.

Lagrange, Université de Nice Sophia-Antipolis et Observatoire de la Cˆote d’Azur, BP 4229, 06304 Nice Cedex 4, France Received 26 September 2011 / Accepted 21 June 2012 ABSTRACT Context. Asymptotic giant branch (AGB) stars are one of the largest distributors of dust into the interstellar medium. However, the wind formation mechanism and dust condensation sequence leading to the observed high mass-loss rates have not yet been constrained well observationally, in particular for oxygen-rich AGB stars. Aims. The immediate objective in this work is to identify molecules and dust species which are present in the layers above the photosphere, and which have emission and absorption features in the mid-infrared (IR), causing the diameter to vary across the N-band, and are potentially relevant for the wind formation. Methods. Mid-IR (8–13 μm) interferometric data of four oxygen-rich AGB stars (R Aql, R Aqr, R Hya, and W Hya) and one carbon- rich AGB star (V Hya) were obtained with MIDI/VLTI between April 2007 and September 2009.
