Discovery of a 9-s X-Ray Pulsar, AX J0049-732, in the Small Magellanic Cloud
Masaru Ueno, Jun Yokogawa, Kensuke Imanishi +1
We report the ASCA discovery of a new X-ray pulsar, AX J0049-732, in the Small Magellanic Cloud (SMC). The pulse shape is sinusoidal with a barycentric period of 9.1320 +/- 0.0004…
Discovery of the Slowest X-Ray Pulsar in the SMC, AX J0049.5-7323, with ASCA
Jun Yokogawa, Kensuke Imanishi, Masaru Ueno +1
The discovery of coherent pulsations with ASCA from an X-ray source, AX J0049.5-7323, is reported. The barycentric period was determined to be 755.5 +/- 0.6 s, which is the longest…
Discovery of 101-s Pulsations from AX J0057.4-7325 in the SMC with ASCA
Jun Yokogawa, Ken'ichi Torii, Takayoshi Kohmura +2
The results from two ASCA observations of AX J0057.4-7325 = RX J0057.3-7325 are presented. Coherent pulsations with a barycentric period of 101.45 +/- 0.07 s were discovered in the…
ASCA Observations of the Twin Supernova Remnants in the Large Magellanic Cloud, DEM L316
Mamiko Nishiuchi, Jun Yokogawa, Katsuji Koyama +1
We report results from an ASCA X-ray study of DEM L316, an emission nebula in the Large Magellanic Cloud (LMC) consisting of two closely-spaced supernova remnants (SNRs). The SIS i…
Discovery of 172-s Pulsations from a Be/X-ray Binary Candidate AX J0051.6-7311 in the SMC with ASCA
Jun Yokogawa, Ken'ichi Torii, Kensuke Imanishi +1
The results from three ASCA observations of AX J0051.6-7311 = RX J0051.9-7311 are reported. Coherent pulsations with a barycentric period of 172.40 +/- 0.03 s were discovered in th…
Discovery of a new pulsating X-ray source with a 1549.1-s period, AX J183220-0840
M. Sugizaki, K. Kinugasa, K. Matsuzaki +3
A new pulsating X-ray source, AX J183220-0840, with a 1549.1-s period was discovered at R.A.= 18h32m20s and Dec.=-8d40'30'' (J2000, uncertainty=0.6degree) during an ASCA observatio…
ASCA Observation of the New Transient X-ray Pulsar XTE J0111.2-7317 in the Small Magellanic Cloud
Jun Yokogawa, Biswajit Paul, Masanobu Ozaki +3
The new transient X-ray pulsar XTE J0111.2-7317 was observed with Advanced Satellite for Cosmology and Astrophysics (ASCA) on 1998 November 18, a few days after its discovery with…
Broad-Band X-Ray Study of a Transient Pulsar RX J0059.2-7138
Makoto Kohno, Jun Yokogawa, Katsuji Koyama
We report on the results of the ASCA and ROSAT observations on RX J0059.2-7138, a transient X-ray pulsar in the Small Magellanic Cloud. The barycentric pulse period has been precis…
Deep X-Ray Observations of Supernova Remnants G359.1-0.5 and G359.0-0.9 with ASCA
Aya Bamba, Jun Yokogawa, Masaaki Sakano +1
We present the results of deep ASCA observations of two shell-like radio supernova remnants (SNRs) located in the direction to the Galactic center (GC) region. Unlike the radio mor…
A Study of the Populations of X-ray Sources in the Small Magellanic Cloud with ASCA
Jun Yokogawa, Kensuke Imanishi, Masahiro Tsujimoto +4
The Advanced Satellite for Cosmology and Astrophysics (ASCA) has made multiple observations of the Small Magellanic Cloud (SMC). X-ray mosaic images in the soft (0.7--2.0 keV) and…
