Quasi-periodic X-ray Flares from the Protostar YLW15
Yohko Tsuboi, Kensuke Imanishi, Katsuji Koyama +2
With ASCA, we have detected three X-ray flares from the Class I protostar YLW15. The flares occurred every ~20 hours and showed an exponential decay with time constant 30-60 ks. Th…
Discovery of an X-Ray Pulsar in the SMC: AX J0058-7203
Masahiro Tsujimoto, Kensuke Imanishi, Jun Yokogawa +1
We report on the discovery and analysis of an X-ray pulsar, AX J0058-7203, in the Small Magellanic Cloud. This pulsar exhibits coherent pulsations at P= 280.3 s with a double-peak…
ASCA Discovery of a Be X-Ray Pulsar in the SMC: AX J0051-733
Kensuke Imanishi, Jun Yokogawa, Masahiro Tsujimoto +1
ASCA observed the central region of the Small Magellanic Cloud, and found a hard X-ray source, AX J0051-733, at the position of the ROSAT source RX J0050.8-7316, which has an optic…
Further studies of 1E 1740.7-2942 with ASCA
Masaaki Sakano, Kensuke Imanishi, Masahiro Tsujimoto +2
We report the ASCA results of the Great Annihilator 1E 1740.7-2942 obtained with five pointing observations in a time span of 3.5 years. The X-ray spectrum for each period is well…
