A Deep Search for Additional Satellites Around the Dwarf Planet
Search for Additional Satellites around Haumea A Preprint typeset using LTEX style emulateapj v. 01/23/15 A DEEP SEARCH FOR ADDITIONAL SATELLITES AROUND THE DWARF PLANET HAUMEA Luke D. Burkhart1,2, Darin Ragozzine1,3,4, Michael E. Brown5 Search for Additional Satellites around Haumea ABSTRACT Haumea is a dwarf planet with two known satellites, an unusually high spin rate, and a large collisional family, making it one of the most interesting objects in the outer solar system. A fully self-consistent formation scenario responsible for the satellite and family formation is still elusive, but some processes predict the initial formation of many small moons, similar to the small moons recently discovered around Pluto. Deep searches for regular satellites around KBOs are difficult due to observational limitations, but Haumea is one of the few for which sufficient data exist. We analyze Hubble Space Telescope (HST) observations, focusing on a ten-consecutive-orbit sequence obtained in July 2010, to search for new very small satellites. To maximize the search depth, we implement and validate a non-linear shift-and-stack method. No additional satellites of Haumea are found, but by implanting and recovering artificial sources, we characterize our sensitivity. At distances between 10,000 km and 350,000 km from Haumea, satellites with radii as small as 10 km are ruled out, assuming∼ an albedo∼ (p 0.7) similar to Haumea. We also rule out satellites larger∼ than &40 km in most of the Hill sphere using≃ other HST data. This search method rules out objects similar in size to the small moons of Pluto. -

Sirius Astronomer Newsletter
SIRIUS ASTRONOMER www.ocastronomers.org The Newsletter of the Orange County Astronomers April 2020 Free to members, subscriptions $12 for 12 issues Volume 47, Number 4 The large galaxy is NGC7331 and shown just to its left are 5 galaxies collectively referred to as the Deer Lick Group. Image by Dave Radosevich and Don Lynn, taken at our Anza site in multiple sessions during 2006 and 2008. It was captured through an 8 inch Maksutov telescope using an SBIG ST8 camera. From the Orange County Astronomers’ Board of Trustees: Response to COVID-19 Crisis The OCA Board of Trustees discussed our best course of action for upcoming events at its March 22, 2020 meeting, including Outreaches, General Meetings, SIG Meetings, Star Parties and all other in-person club events. We are cancelling all of these club events through the end of May, 2020 to help reduce exposure to the COVID-19 virus and in response to the orders from Governor Newsom and the state Health Department. Chapman University has cancelled our meetings through the end of May as part of its response to the crisis, so these general meetings could not go forward there anyway. We are exploring the possibility of holding at least part of our April and May meetings online, particularly the guest lectures. The details will be posted to the website, email groups and social media when they become available. Please check the OCA website periodically for updates, as the information should be posted there first. Star parties are now cancelled through the end of May. This includes both the Anza Star Parties and Orange County star parties. -

Asteroid Precovery. a Citizen-Science Project Using the Virtual Observatory
Highlights of Spanish Astrophysics VII, Proceedings of the X Scientific Meeting of the Spanish Astronomical Society held on July 9 - 13, 2012, in Valencia, Spain. J. C. Guirado, L.M. Lara, V.

Astrofisica, CAB (INTA-CSIC), ESAC Campus. P.O. Box 78. 28691 Villanueva de la Ca~nada,Madrid, Spain 2 Spanish Virtual Observatory (SVO) Abstract Precovery is the process of finding an astronomical object in archive data taken before the discovery of the object. The Virtual Observatory project makes it much easier to access large collection of images in astronomical archives and, thus, opens the possibility to explore them to find more information about certain objects, for instance, Near Earth Asteroids. We have started a citizen-science project that combines some automatic algorithms, Virtual Observatory techniques and the participation of many people that, not being professional astronomers, help to find professional results and make a significant contribution to the accurate knowledge of the orbits of NEAs. The project started in July 2011 and during its first year more than 3000 registered users have collaborated to make more than 164.000 measurements corresponding to around 7600 archive images and 1000 different NEAs. As a result of this work, around 2300 new data, for more than 500 objects, have been submitted to the Minor Planet Center for publication. The great reception of the system as well as the results obtained makes it a valuable and reliable tool for improving the orbital parameters of Near Earth Asteroids. -

Interstellar Interlopers Two Recently Sighted Space Rocks That Came from Beyond the Solar System Have Puzzled Astronomers

InterstellarInterlopers Interlopers Two recently sighted space rocks that came from beyond the solar system have puzzled astronomers By David Jewitt and Amaya Moro-Martín Illustrations by Ron Miller October 2020, ScientificAmerican.com 43 © 2020 Scientific American David Jewitt is an astronomer at the University of California, Los Angeles, where he studies the primitive bodies of the solar system and beyond. Amaya Moro-Martín is an astronomer at the Space Telescope Science Institute in Baltimore. She investigates planetary systems and extrasolar comets. ATE IN THE EVENING OF OCTOBER 24, 2017, AN E-MAIL ARRIVED CONTAINING tantalizing news of the heavens. Astronomer Davide Farnocchia of NASA’s Jet Propulsion Laboratory was writing to one of us (Jewitt) about a new object in the sky with a very strange trajectory. Discovered six days earli- er by University of Hawaii astronomer Robert Weryk, the object, initially dubbed P10Ee5V, was traveling so fast that the sun could not keep it in orbit. Instead of its predicted path being a closed ellipse, its orbit was open, indicating that it would never return. “We still need more data,” Farnocchia wrote, “but the orbit appears to be hyperbolic.” Within a few hours, Jewitt wrote to Jane Luu, a long-time collaborator with Norwegian connections, about observing the new object with the Nordic Optical Telescope in LSpain. -
