Upper limits to the number of Oort Cloud Objects based on serendipitous occultation events search in X-rays
Hsiang-Kuang Chang, Chih-Yuan Liu, Jie-Rou Shang
Using all the RXTE archival data of Sco X-1 and GX 5-1, which amount to about 1.6 mega seconds in total, we searched for possible occultation events caused by Oort Cloud Objects. T…
A Possible 55-day X-ray Period of the Ultraluminous Accreting Pulsar M82 X-2
A. K. H. Kong, C. -P. Hu, L. C. -C. Lin +4
We report a possible detection of a 55-day X-ray modulation for the ultraluminous accreting pulsar M82 X-2 from archival Chandra observations. Because M82 X-2 is known to have a 2.…
Search for serendipitous TNO occultation in X-rays
Hsiang-Kuang Chang, Chih-Yuan Liu, Kuan-Ting Chen
To study the population properties of small, remote objects beyond Neptune's orbit in the outer solar system, of kilometer size or smaller, serendipitous occultation search is so f…
Millisecond dips in the 2007-2009 RXTE/PCA lightcurve of Sco X-1 and one possible occultation event
Hsiang-Kuang Chang, Chih-Yuan Liu, Kuan-Ting Chen
Serendipitous stellar occultation search is so far the only way to detect the existence of very small, very dim, remote objects in the solar system. To date, however, there are onl…
Millisecond dip events in the 2007 RXTE/PCA data of Sco X-1 and the TNO size distribution
Chih-Yuan Liu, Hsiang-Kuang Chang, Jau-Shian Liang +1
Millisecond dips in the RXTE/PCA archival data of Sco X-1 taken from 1996 to 2002 were reported recently. Those dips were found to be most likely caused by instrumental dead time b…
Millisecond dips in the RXTE/PCA light curve of Sco X-1 and TNO occultation
Hsiang-Kuang Chang, Jau-Shian Liang, Chih-Yuan Liu +1
Millisecond dips in the RXTE/PCA light curve of Sco X-1 were reported recently (Chang et al. 2006), which were interpreted as the occultation of X-rays from Sco X-1 caused by Trans…
