Backyard Worlds: Search for Planet 9

Post by bystander » Mon Mar 27, 2017 5:03 pm

Citizen Search for New Planet in Solar System
Australian National University | 2017 Mar 27

ANU is launching a search for a new planet in our Solar System, inviting anyone around the world with access to the Internet to help make the historic discovery.

Anyone who helps find the so-called Planet 9 will work with ANU astronomers to validate the discovery through the International Astronomical Union. ...

"We have the potential to find a new planet in our Solar System that no human has ever seen in our two-million-year history," said Dr Tucker from the ANU Research School of Astronomy and Astrophysics. ...

"Planet 9 is predicted to be a super Earth, about 10 times the mass and up to four times the size of our planet. It's going to be cold and far away, and about 800 times the distance between Earth and the sun. It's pretty mysterious," he said.

The ANU project will allow citizen scientists to use a website to search hundreds of thousands of images taken by the ANU SkyMapper telescope at Siding Spring. ...

AMNH: Citizen Scientists Uncover a Cold New World Near the Sun

A new citizen-science tool released earlier this year to help astronomers pinpoint new worlds lurking in the outer reaches of our solar system has already led to a discovery: a brown dwarf a little more than 100 light years away from the Sun. Just six days after the launch of the Backyard Worlds: Planet 9 website in February, four different users alerted the science team to the curious object, whose presence has since been confirmed via an infrared telescope. ...

Days after the Backyard Worlds website debuted on February 15, Bob Fletcher, a science teacher in Tasmania, identified a very faint object moving across the WISE images. It was soon also flagged by three other citizen scientists from Russia, Serbia, and the United States. After some initial investigation by the research team, which originally called the object “Bob’s dwarf,” Faherty was awarded time on NASA's Infrared Telescope Facility in Hawaii, where she confirmed that it was a previously unknown brown dwarf just a few hundred degrees warmer than Jupiter. The authors say that sky surveys had missed this object because it’s too faint. All four volunteers are co-authors on the scientific paper announcing the discovery. ...

NOAO: Citizen Scientists Invited to Join Quest for New Worlds

Citizen Scientists Invited to Join Quest for New Worlds
National Optical Astronomy Observatory | 2019 Feb 19
The Backyard Worlds: Planet 9 project re-launches this week, with a call to volunteer citizen scientists to join the search for cold worlds near the Sun. With its newly revamped online interface and equipped with twice as much data as before, the project offers new opportunities to discover planets lurking yet unseen in the outer reaches of the Solar System (e.g., Planet 9, Planet X) as well as cold nearby “failed stars” (a.k.a. brown dwarfs). The re-launch coincides with the publication of the project’s latest discovery: a record-setting white dwarf star encircled by mysterious dusty rings that challenge astronomers to rethink the long-term evolution of planetary systems. ...

Alongside its re-launch, Backyard Worlds also announces its latest discovery, a surprising object unlike anything the team expected to find. Whereas most Backyard Worlds discoveries have been brown dwarfs, this newly published member of the solar neighborhood is a white dwarf – the faint, dense remnant of a stellar death long ago.

The white dwarf in question – LSPM J0207+3331, or J0207 for short – is unusually bright in WISE images, indicating that it’s encircled by a warm, dusty circumstellar disk. Such disks are thought to result from the ongoing breakup of small rocky planetesimals in orbit around the white dwarf. But with an age of roughly 3 billion years, J0207 is colder and nearly three times older than any other white dwarf known to harbor such a disk. ...

Citizen Scientists Help Locate Some of the Coolest Brown Dwarfs Ever Discovered

represents the white dwarf (the remnant of a long-dead sun-like star), while the
brown/orange foreground object is the newly discovered brown dwarf companion.

scientists because it lies right within the plane of the Milky Way.

How complete is our census of the Sun’s closest neighbors? Astronomers and a team of data-sleuthing volunteers participating in Backyard Worlds: Planet 9, a citizen science project, have discovered roughly 100 cool worlds near the Sun — objects more massive than planets but lighter than stars, known as brown dwarfs.

With the help of W. M. Keck Observatory on Maunakea in Hawaii, the research team found several of these newly discovered worlds are among the very coolest known, with a few approaching the temperature of Earth — cool enough to harbor water clouds. ...

Discovering and characterizing astronomical objects near the Sun is fundamental to our understanding of our place in, and the history of, the universe. Yet astronomers are still unearthing new residents of the solar neighborhood. The new Backyard Worlds discovery bridges a previously empty gap in the range of low-temperature brown dwarfs, identifying a long-sought missing link within the brown dwarf population. ...
