Such HVSs are believed to be ejected from the Galactic centre (GC) through tidal disruption of a binary by the super-massive black hole (Hills mechanism). The Hyper-MUCHFUSS survey aims at finding high-velocity potentially unbound hot subdwarf stars. We present the spectroscopic and kinematical analyses of a He-sdO as well as three candidates among the sdB stars using optical Keck/ESI and VLT (X-shooter, FORS) spectroscopy.

We find 87 reliable detections after filtering for the signal-to-noise ratio of the Yarkovsky drift esti- mate and making sure the estimate is compatible with the physical properties of the analyzed object. Furthermore, we find a list of 24 marginally significant detec- tions, for which future astrometry could result in a Yarkovsky detection. A further outcome of the filtering procedure is a list of detections that we consider spurious because unrealistic or not explicable with the Yarkovsky effect. Among the smallest asteroids of our sample, we determined four detections of solar radiation pressure, in addition to the Yarkovsky effect. As the data volume increases in the near fu- ture, our goal is to develop methods to generate very long lists of asteroids with reliably detected Yarkovsky effect, with limited amounts of case by case specific adjustments.

The near-Earth object (NEO) population is a window into the original conditions of the protosolar nebula, and has the potential to provide a key pathway for the delivery of water and organics to the early Earth. In addition to delivering the crucial ingredients for life, NEOs can pose a serious hazard to humanity since they can impact the Earth. To properly quantify the impact risk, physical properties of the NEO population need to be studied. Unfortunately, NEOs have a great variation in terms of mitigation- relevant quantities (size, albedo, composition, etc.) and less than 15% of them have been characterized to date.

  • Near-Earth Objects
    Near-Earth Objects 12/06/96 shows an elongated object about seen here in a NEAR spacecraft image 4.5 kilometers in extent. Veverka et al. (2000), Science, 289, Ostro et al. (1999), Icarus, 137: pp. 122-139. pp. 2088-2097. THE NEAR EARTH OBJECT POPULATION Near-Earth objects are an important area of study because they are relatively primitive bodies left over from the early solar system formation process, they can be utilized as raw materials for building future structures and habitats within the inner solar system, and their rare, but potentially catastrophic, collisions with Earth make them potential hazards. A comprehensive search for near-Earth objects (NEOs) not only ensures that there will be no surprises from Earth threatening objects but there will be new discoveries. During future close Earth approaches, these objects can be studied via ground-based programs including radar "imaging" characterizations and Earth orbital satellite observations (e.g., Hubble Space Telescope). In addition, these NE0 discoveries will provide future mission targets that are among the most accessible in terms of spacecraft energy requirements. Indeed, many near-Earth asteroids present easier rendezvous and landing opportunities than Earth's own Moon. While the vast majority of the rocky asteroids reside between the orbits of Mars and Jupiter and almost all the icy comets are resident in the so-called Kuiper belt and Oort cloud in the outer solar system, a significant number of these bodies reside in the Earth's neighborhood. Near-Earth asteroids and near-Earth comets make up the population of so-called near-Earth objects (NEOs).

The astrometry collected during the 2019 apparition provides information on the trajectory of (410777) by constraining the Yarkovsky effect, which is the main source of uncertainty for future predictions, and informing the impact hazard assessment. We included the Yarkovsky effect in the force model and estimated its magnitude from the fit to the (410777) optical and radar astrometric data. We performed the (410777) hazard assessment over 200 years by using two independent approaches: the NEODyS group adopted a generalisation of the Line Of Variations method in a 7-dimensional space, whereas the JPL team resorted to the Multilayer Clustered Sampling technique.

    Draft version August 19, 2020 Typeset using LATEX twocolumn style in AASTeX63 Revised and new proper motions for confirmed and candidate Milky Way dwarf galaxies Alan W. McConnachie1 and Kim A. Venn2 1NRC Herzberg Astronomy and Astrophysics, 5071 West Saanich Road, Victoria, B.C., Canada, V9E 2E7 2Physics & Astronomy Department, University of Victoria, 3800 Finnerty Rd, Victoria, B.C., Canada, V8P 5C2 ABSTRACT A new derivation of systemic proper motions of Milky Way satellites is presented, and applied to 59 confirmed or candidate dwarf galaxy satellites using Gaia Data Release 2. This constitutes all known Milky Way dwarf galaxies (and likely candidates) as of May 2020 except the Magellanic Clouds, the Canis Major and Hydra 1 stellar overdensities, and the tidally disrupting Bootes III and Sagittarius dwarf galaxies. We derive systemic proper motions for the first time for Indus 1, DES J0225+0304, Cetus 2, Pictor 2 and Leo T, but note that the latter three rely on photometry that is of poorer quality than for the rest of the sample. We cannot resolve a signal for Bootes 4, Cetus 3, Indus 2, Pegasus 3, or Virgo 1. Our method is inspired by the maximum likelihood approach of Pace & Li(2019) and examines simultaneously the spatial, color-magnitude, and proper motion distribution of sources. Systemic proper motions are derived without the need to identify confirmed radial velocity members, although the proper motions of these stars, where available, are incorporated into the analysis through a prior on the model. The associated uncertainties on the systemic proper motions are on average a factor of ∼ 1:4 smaller than existing literature values.

  • Orion® Intelliscope® Computerized Object Locator
    INSTRUCTION MANUAL Orion® IntelliScope® Computerized Object Locator #7880 Providing Exceptional Consumer Optical Products Since 1975 Customer Support (800) 676-1343 E-mail: [email protected] Corporate Offices (831) 763-7000 89 Hangar Way, Watsonville, CA 95076 IN 229 Rev. G 01/09 Congratulations on your purchase of the Orion IntelliScope™ Com­ pu ter ized Object Locator. When used with any of the SkyQuest IntelliScope XT Dobsonians, the object locator (controller) will provide quick, easy access to thousands of celestial objects for viewing with your telescope. Coil cable jack The controller’s user-friendly keypad combined with its database of more than 14,000 RS-232 jack celestial objects put the night sky literally at your fingertips. You just select an object to view, press Enter, then move the telescope manually following the guide arrows on the liquid crystal display (LCD) screen. In seconds, the IntelliScope’s high-resolution, 9,216- step digital encoders pinpoint the object, placing it smack-dab in the telescope’s field of Backlit liquid-crystal display view! Easy! Compared to motor-dependent computerized telescopes systems, IntelliScope is faster, quieter, easier, and more power efficient. And IntelliScope Dobs eschew the complex initialization, data entry, or “drive training” procedures required by most other computer- ized telescopes. Instead, the IntelliScope setup involves simply pointing the scope to two bright stars and pressing the Enter key. That’s it — then you’re ready for action! These instructions will help you set up and properly operate your Intelli Scope Com pu ter- ized Object Locator. Please read them thoroughly. Table of Contents 1.

(Roger Romani) Approved for the University Committee on Graduate Studies iii \Two things fill the mind with ever-increasing wonder and awe, the more often and the more intensely the mind of thought is drawn to them: the starry heavens above me and the moral law within me." { Immanuel Kant iv Abstract Pulsars are rapidly-rotating neutron stars born out of the death of stars. A diffuse nebula is formed when particles stream from these neutron stars and interact with the ambient medium. These pulsar wind nebulae (PWNe) are visible across the electro- magnetic spectrum, producing some of the most brilliant objects ever observed.
