IGRINS Near-IR High-Resolution Spectroscopy of Multiple Jets around LkH 234
Heeyoung Oh, Tae-Soo Pyo, In-Soo Yuk +18
We present the results of high-resolution near-IR spectroscopy toward the multiple outflows around the Herbig Be star Lk{\Ha} 234 using the Immersion Grating Infrared Spectrograph…
High-resolution X-ray Spectroscopy of BD +30 3639
Joel H. Kastner, Young Sam Yu, John Houck +3
We present preliminary results from the first X-ray gratings spectrometer observations of a planetary nebula (PN). We have used the Chandra X-ray Observatory Low Energy Transmissio…
Inner warm disk of ESO H 279A revealed by NA I and CO overtone emission lines
A-Ran Lyo, Jongsoo Kim, Jae-Joon Lee +20
We present analysis of near-infrared, high-resolution spectroscopy towards the Flat-spectrum YSO (Young Stellar Object) ESO H 279a (1.5 solar mass) in the Serpens star forming…
The X-Ray Spectrum of a Planetary Nebula at High Resolution: Chandra Gratings Spectroscopy of BD+30 3639
Young Sam Yu, Raanan Nordon, Joel H. Kastner +3
We present the results of the first X-ray gratings spectroscopy observations of a planetary nebula (PN), the X-ray-bright, young BD+30 3639. We observed BD+30 3639 for a total of 3…
Narrow Radiative Recombination Continua: A Signature of Ions Crossing the Contact Discontinuity of Astrophysical Shocks
Raanan Nordon, Ehud Behar, Noam Soker +2
X-rays from planetary nebulae (PNs) are believed to originate from a shock driven into the fast stellar wind (v ~ 1000 km/s) as it collides with an earlier circumstellar slow wind…
