Spectroscopic Observations of Ten Galactic Wolf-Rayet Stars at Bosscha Observatory:Determination of Stellar Parameters and Mass-loss Rates
《Research in Astronomy and Astrophysics》2024年第9期7-27,共21页Hakim Luthfi Malasan Bakuh Danang Setyo Budi 
supported through HLM’s Program Penelitian Pengabdian Masyarakat ITB(P2MI)Astronomy Division,FMIPA ITB grant 2022-2023;Support for MAST for non-HST data is provided by the NASA Office of Space Science via grant NNX13AC07G and by other grants and contracts。
We present optical spectra of 10 Galactic Wolf-Rayet(WR)stars that consist of five WN and five WC stars.The optical observation was conducted using a low-resolution spectrograph NEO-R1000(λ/Δλ~1000)at GAO-ITB RTS(2...

Physical and Kinematical Characteristics of Wolf–Rayet Central Stars and their Host Planetary Nebulae
《Research in Astronomy and Astrophysics》2023年第9期219-240,共22页Z.Awad A.Ali 
the European Space Agency(ESA)mission Gaia,processed by the Gaia Data Processing and Analysis Consortium(DPAC).This research has made use of the SIMBAD database,operated at CDS,Strasbourg,France.
We address the physical and kinematical properties of Wolf–Rayet[WR]central stars(CSs)and their host planetary nebulae(PNe).The studied sample comprises all[WR]CSs that are currently known.The analysis is based on re...

Polarization variability arising from clumps in the winds of Wolf-Rayet stars被引量：1
《Chinese Journal of Astronomy and Astrophysics》2009年第5期558-576,共19页Qing-Kang Li Joseph E Cassinelli John C. Brown Richard Ignace 
the National NaturalScience Foundation of China (grant Nos. 10273002, 10573022 and 10778601 (QL));the NSF Center forMagnetic Self Organization in Laboratory and Astrophysics Plasmas (JPC);UK STFC Rolling Grant(JCB). JPC and RI have been supported in part by award TM3-4001 issued by the Chandra X-rayObservatory Center.
Polarimetric and photometric variability of Wolf-Rayet （WR） stars as caused by clumps in the winds is revisited. In our model, which is improved from Li et al., radial expansion of the thickness is accounted for, bu...

DISCOVERY OF A NEW PLANETARY NEBULA WITH [WC11] CORE STAR: IRAS 19367+2458
《Chinese Science Bulletin》1992年第3期213-216,共4页胡景耀 董怡荪 
Planetary nebulae are the progenetors of white dwarfs in the final evolution stage of stars with intermediate initial mass ( 1M_⊙<M_*<9M_⊙). The planetary nebulae can be devided into different groups according...
