An improved solution to geometric distortion using an orthogonal method
Wang, Na; Peng, Huan-Wen; Peng, Qing-Yu
The geometric distortion of a CCD field of view has a direct influence on the positional measurements of CCD observations. In order to obtain high precision astrometric results, the geometric distortion should be derived and corrected precisely. As presented in our previous work, a convenient solution has been carried out and has also been applied…
Akari, SCUBA2 and Herschel Data of Pre-Stellar Cores

First Characterization of the Neutral ISM in Two Local Volume Dwarf Galaxies
Cannon, John M.; Mizener, Andrew; Bralts-Kelly, Lilly +9 more
We present the first H I spectral-line images of the nearby, star-forming dwarf galaxies UGC 11411 and UGC 8245, acquired as part of the “Observing for University Classes” program with the Karl G. Jansky Very Large Array (VLA). These low-resolution images localize the H I gas and reveal the bulk kinematics of each system. Comparing with Hubble Spa…
Photometric Strömgren-Hβ Quantification for O and B Stars of Luminosity Class V
Paunzen, Ernst; Kaltcheva, Nadia; Golev, Valeri
In any photometric system, the relationship between the spectral type and the intrinsic colors is fundamental for the photometric stellar classification and for a reliable derivation of stellar parameters. Such relationships are being constantly verified and improved based on larger and better samples. The capability of the Strömgren-Hβ photometry…
Quasiperiodic field-aligned current dynamics associated with auroral undulations during a substorm recovery
Marghitu, O.; Vogt, J.; Bunescu, C. +2 more
A substorm recovery event in the early morning sector is explored by means of ground and spacecraft data. The ground data are provided by stations of the MIRACLE network, in northern Scandinavia and Svalbard, while spacecraft data are observed by the Cluster satellites, toward the end of the recovery phase. Additional information is provided by th…
Comet 67P/C-G seen through Osiris, the eyes of Rosetta
Barbieri, Cesare
The present paper will describe some of the highlights obtained by the imaging system Osiris on board the European spacecraft Rosetta during its cruise around comet 67P/Churyumov-Gerasimenko. Some results obtained by other instruments, including ground telescopes, will be briefly mentioned. The immense archive of data obtained during such unique c…
Latitude dependence of the solar granulation during the minimum of activity in 2009
Utz, D.; Hanslmeier, A.; Muller, R.
Context. Knowledge of the latitude variation of the solar granulation properties (contrast and scale) is useful to better understand interactions between magnetic field, convection, differential rotation, and meridional circulation in the solar atmosphere.
Aims: We investigated the latitude dependence of the contrast and scale of the solar gr…
Accuracy of Mykolaiv Asteroid Observations with Different Reference Catalogues
Maigurova, N. V.; Pomazan, A. V.; Bodryagin, D. V. +1 more
The results of astrometric reductions of main belt asteroid observations with usage of 3 different reference catalogues are presented. The high precision catalogs CMC15, UCAC4 and GAIA DR1 were used as reference catalogues for calculation asteroid equatorial coordinates. The asteroid observations were carried out at KT-50 telescope of the RI "MAO"…
The Radio-Far Infrared Correlation in the NEP Deep Field
Pearson, Chris; Barrufet, Laia; Serjeant, Stephen +6 more
We report the results of a multi-wavelength study in the North Ecliptic Pole (NEP) deep field and examine the far infrared-radio correlation (FIRC) for high and low redshift objects. We have found a correlation between the GMRT data at 610 MHz and the Herschel data at 250 µm that has been used to define a spectral index. This spectral index …
