Study of the star catalogue (epoch AD 1396.0) recorded in ancient Korean astronomical almanac

Jeon, Junhyeok; Lee, Yong Bok; Lee, Yong-Sam

The study of old star catalogues provides important astrometric data. Most of the researches based on the old star catalogues were manuscript published in Europe and from Arabic/Islam. However, the old star catalogues published in East Asia did not get attention. Therefore, among the East Asian star catalogues we focus on a particular catalogue re…

Chandra, XMM-Newton and HST observations of a transient in M31 with a possible asymmetric, precessing disc

Murray, S. S.; Garcia, M. R.; Barnard, R.

The transient X-ray source CXOM31 004205.77+411330.43 exhibited several outbursts during our long-term monitoring campaign of approximately monthly observations of the M31 centre with Chandra. However, the decay profile appears to be unlike those observed from Galactic transients. We followed up the 2011 outburst with two ∼B band HST/ACS observati…

X-ray photometry

Page, M. J.

I describe a method for synthesizing photometric passbands for use with current and future X-ray instruments. The method permits the standardization of X-ray passbands and thus X-ray photometry between different instruments and missions. The method is illustrated by synthesizing a passband in the XMM-Newton European Photon Imaging Camera pn which …
