We present new images and photometry of the massive star-forming complex Cygnus X obtained with the Infrared Array Camera (IRAC) and the Multiband Imaging Photometer for Spitzer (MIPS) on board the Sp...
Brightness and Fluctuation of the Mid-Infrared Sky from AKARI Observations towards the North Ecliptic Pole
Brightness Fluctuation Mid-Infrared Sky AKARI Observations the North Ecliptic Pole
2012/2/21
We present the smoothness of the mid-infrared sky from observations by the Japanese infrared astronomical satellite AKARI. AKARI monitored the north ecliptic pole (NEP) during its cold phase with nine...
PTF10nvg: An Outbursting Class I Protostar in the Pelican/North American Nebula
stars formation – stars pre-main sequence
2010/11/15
During a synoptic survey of the North American Nebula region, the Palomar Transient Factory
(PTF) detected an optical outburst (dubbed PTF10nvg) associated with the previously unstudied
flat or risi...
Optical Images and Source Catalog of AKARI North Ecliptic Pole Wide Survey Field
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
We present the source catalog and the properties of the $B-, R-$, and $I-$band images obtained to support the {\it AKARI} North Ecliptic Pole Wide (NEP-Wide) survey. The NEP-Wide is an {\it AKARI} inf...
North–South Distribution of Solar Flares during Cycle 23
activity flares north south asymmetry
2010/9/16
In this paper, we investigate the spatial distribution of solar flares in the northern and southern hemispheres of the Sun that occurred during the period 1996 to 2003. This period of investigation in...
Spectroscopic Binaries near the North Galactic Pole Paper 12A: 6 Boötis
Radial velocities—spectroscopicbinaries—orbits—stars
2010/9/15
About 25 years ago, in Paper 12 of this series, the author presented a spectroscopic orbit for 6 Boo. The velocity amplitude of little more than 1 km s−1 was much smaller than for any star whose...
Recent aeolian erosion and deposition in the north polar plateau of Mars
aeolian erosion Mars north polar plateau
2009/6/1
We have identified extensive dark regions in the north polar plateau of Mars, which are largely free of surface water-ice. We propose that represent zones of recent sedimentary accumulation.
Spectroscopic Binaries near the North Galactic Pole Paper 24: HD 106104, 109281, 109463 and 110743
Radial velocities spectroscopic binaries
2009/5/20
The four stars treated in this paper have been under observation
with photoelectric radial-velocity spectrometers for many years. They have
proved to be binaries with periods of 30, 1828, 1514 and 8...
