A Circumbinary Debris Disk in a Polluted White Dwarf System

NASA's SDO Adds Leap Second to Master Clock
https://www.nasa.gov/...re/goddard/2016/space-timekeeping-nasas-sdo-adds-leap-second-to-master-clock
On Dec. 31, 2016, official clocks around the world will add a leap second just before midnight Coordinated Universal Time — which corresponds to
6:59:59 p.m. EST. NASA missions will also have to make the switch, including the Solar Dynamics Observatory, or SDO, which watches the sun 24/7.

"SDO moves about 1.9 miles every second," said Dean Pesnell, the project scientist for SDO at NASA's Goddard Space Flight Center in Greenbelt,
Maryland. "So does every other object in orbit near SDO. We all have to use the same time to make sure our collision avoidance programs are accurate.
So we all add a leap second to the end of 2016, delaying 2017 by one second."

Space Shredder: Sun May Be Tearing Asteroids Apart
http://www.space.com/35180-sun-shredding-asteroids-to-pieces.html

With a cloud of trailing debris, a rocky object known as 3200 Phaethon straddles the line between asteroid and comet.
But the space rock's days, it seems, might be numbered. New research suggests that the sun may be slowly shredding
Phaethon to pieces due to its close orbit. The same may be happening to another close-orbiting object.

Pulsations detected in a hot, helium-atmosphere white dwarf
http://phys.org/news/2016-12-pulsations-hot-helium-atmosphere-white-dwarf.html

Astronomers have recently discovered non-radial oscillations in a hot, helium-atmosphere white dwarf designated PG 0112+104.
The newly detected 11 independent pulsation modes in this white dwarf could be essential for researchers testing the radial
differential rotation and internal compositional stratification of highly evolved stellar remnants. The findings were
presented in a paper published Dec. 22 on the arXiv pre-print server.

Last 5 Sept. 2016, asteroid (17473) Freddiemercury has been officially named by the International Astronomical Union after Freddie Mercury,
the lead vocalist and co-principal songwriter of the epic rock band Queen. It was announced on the occasion of the 70th birthday of Freddie.

Concentric rings found in the debris disk of a young nearby star
http://phys.org/news/2016-12-debris-disk-young-nearby-star.html

An international team of researchers reports the discovery of a series of concentric rings in the debris disk around a young nearby star known as HIP 73145.
These unusual substructures could provide new details about the evolution of circumstellar disks around young stars. The findings were presented in a paper
published Dec. 22 on arXiv.org.

Located some 400 light years away, HIP 73145 (also known as HD 131835) is a 15-million-year-old star with a spectral type of A2IV. It belongs to the Upper
Centaurus Lupus (UCL) moving group, which is part of the Scorpius–Centaurus association. The star is about 70 percent more massive than the sun and has
a radius of 1.38 solar radii. Importantly, HIP 73145 is known to host a debris disk with a radius of approximately 96 AU.

Wait a moment: 2016 goes a little longer thanks to a leap second
https://theconversation.com/wait-a-moment-2016-goes-a-little-longer-thanks-to-a-leap-second-70583

To the time-poor of the world: take heart, for 2016 is a generous year. Not only were you granted a leap day on 29 February,
you will soon score a New Year’s Eve countdown bonus, a leap second, to hold off 2017 for a final sip or regret.

Whereas leap years add a day to align the calendar with the seasons, leap seconds align our everyday clocks with the Sun’s
position in the sky, that is, with the Earth’s rotation.

Currently our planet takes roughly 86,400.00183 seconds (on average) to turn, instead of the expected 86,400 seconds you get
by multiplying 24 hours by 60 minutes by 60 seconds. This may not sound like a great difference, but it amounts to a full
second every 18 months. If left unchecked, it would become noticeable over time, and ultimately become problematic.
