Stellar Population near NGC 2021: Procession of Star Formation in the South Rim of Supergiant Shell LMC 4
Po-Sheng Ou, Rui-Ching Chao, You-Hua Chu +2
Supergiant shells (SGSs) are the largest interstellar structures where heated and enriched gas flows into the host galaxy's halo. The SGSs in the Large Magellanic Cloud (LMC) are s…
Synthetic X-ray emission from white dwarf accreting planetary material
S. Estrada-Dorado, V. Lora, J. A. Toalá +4
The emission of hard X-rays associated with white dwarfs (WD) can be generated by the presence of a stellar companion either by the companion's coronal emission or by an accretion…
New Insights on 30 Dor B Revealed by High-Quality Multi-wavelength Observations
Wei-An Chen, Chuan-Jui Li, You-Hua Chu +4
The supernova remnant (SNR) 30 Dor B is associated with the \ion{H}{2} region ionized by the OB association LH99. The complex interstellar environment has made it difficult to stud…
Chandra observations of the planetary nebula IC 4593
J. A. Toalá, M. A. Guerrero, L. Bianchi +2
The ACIS-S camera on board the Chandra X-ray Observatory has been used to discover a hot bubble in the planetary nebula (PN) IC4593, the most distant PN detected by Chandra so far.…
The Bubble Nebula NGC 7635 -- testing the wind-blown bubble theory
J. A. Toalá, M. A. Guerrero, H. Todt +5
We present a multiwavelength study of the iconic Bubble Nebula (NGC 7635) and its ionising star BD602522. We obtained XMM-Newton EPIC X-ray observations to search for…
On the apparent absence of WR+NS systems: the curious case of WR124
J. A. Toala, L. M. Oskinova, W. -R. Hamann +8
Among different types of massive stars in advanced evolutionary stages is the enigmatic WN8h type. There are only a few Wolf-Rayet (WR) stars with this spectral type in our Galaxy.…
