The H Halo Distribution of 10 Nearby Planetary Nebulae based on the SHASSA Imaging Data

Chih Hao Hsia, Jin Zeng Li, Wing-Huen Ip

Here we present initial results of our search for extensive halos around the planetary nebulae (PNe) in our Galaxy based on imaging data from the Southern H-Alpha Sky Survey Atlas…

Testing the External Shock Model of Gamma-Ray Bursts using the Late-Time Simultaneous Optical and X-ray Afterglows

Yuji Urata, Ryo Yamazaki, Takanori Sakamoto +21

We study the ``normal'' decay phase of the X-ray afterglows of gamma-ray bursts (GRBs), which follows the shallow decay phase, using the events simultaneously observed in the R-ban…

The Evidence for a Binary origin of the Young Planetary Nebula HB 12

Chih Hao Hsia, Wing Huen Ip, Jin Zeng Li

The young planetary nebulae play an important role in stellar evolution when intermediate- to low-mass stars (0.8 8 M) evolve from the proto-planetary nebulae phase…
