The asteroid (3200) Phaethon is widely recognized as the parent of the Geminid meteoroid stream. However, it has never shown evidence for ongoing mass loss or for any form of comet-like activity that would indicate the continued replenishment of the stream. Following an alert by Battams & Watson, we used NASA’s STEREOA spacecraft to image Phaethon near perihelion, in the period UT 2009 June 17‐22, when the heliocentric distance was near 0.14 AU. The resulting photometry shows an unexpected… Expand

RECURRENT PERIHELION ACTIVITY IN (3200) PHAETHON
We present a study of planet-crossing asteroid (3200) Phaethon at three successive perihelia in 2009, 2010, and 2012, using the NASA STEREO spacecraft. Phaethon is clearly detected in 2009 and 2012,Expand
THE DUST TAIL OF ASTEROID (3200) PHAETHON
We report the discovery of a comet-like tail on asteroid (3200) Phaethon when imaged at optical wavelengths near perihelion. In both 2009 and 2012, the tail appears {approx}>350'' (2.5Expand
Characteristics of the 2012 Geminids
The parent of the Geminids, 3200 Phaethon, is a unique body in that it is classified as an asteroid, however is responsible for one of the most prolific meteor showers of the year and has shownExpand
On the possible ejection of meteoroids from asteroid (3200) Phaethon in 2009
Asteroid (3200) Phaethon is the supposed parent body for the Geminid meteoroid stream and previously it has never shown any trace of activity. However, it doubled its brightness unexpectedly andExpand
A study of photometric observations of (3200) phaethon from Lulin Observatory
Abstract The near-Earth asteroid (3200) Phaethon is regarded as the parent body of the Geminid meteor stream. It is also an active asteroid with a very blue spectrum which is similar to that of theExpand
Mass-shedding Activities of Asteroid (3200) Phaethon Enhanced by Its Rotation
Asteroid (3200) Phaethon, a B-type asteroid, has been active during its perihelion passages. This asteroid is considered to be a source of the Geminid meteor stream. It is reported that this asteroidExpand
High-resolution Thermal Infrared Imaging of 3200 Phaethon
We present thermal infrared observations of the active asteroid (and Geminid meteoroid stream parent) 3200 Phaethon using the Very Large Telescope. The images, at 10.7 micron wavelength, were takenExpand
Extremely strong polarization of an active asteroid (3200) Phaethon
TLDR
Polarimetric observation of Phaethon over a wide range of solar phase angle and it is revealed that the asteroid exhibits a very strong linear polarization, implying that Phoethon’s geometric albedo is lower than the current estimate obtained through radiometric observation. Expand
Near-infrared observations of active asteroid (3200) Phaethon reveal no evidence for hydration
TLDR
It is shown that the northern hemisphere and the equatorial region of this asteroid reveal no evidence of hydration in the near-infrared spectra, suggesting that Phaethon’s modern activity is not due to volatile sublimation or devolatilization of phyllosilicates on its surface. Expand
Dynamical Evolution and Thermal History of Asteroids (3200) Phaethon and (155140) 2005 UD
The near-Earth objects (NEOs) (3200) Phaethon and (155140) 2005 UD are thought to share a common origin, with the former exhibiting dust activity at perihelion that is thought to directly supply theExpand
