Discovery of Two Cyclotron Resonance Scattering Features in X-ray Pulsar Cen X-3 by Insight-HXMT
W. Yang, W. Wang, Q. Liu +4
We present the results of the neutron star X-ray binary system Cen X-3 performed by -HXMT with two observations during 2017 and 2018. During these two observations, the so…
Intermediate-band Surface Photometry of the Edge-on Galaxy: NGC 4565
Hong Wu, Dave Burstein, Zugan Deng
We present a deep, 42.79 hr image of the nearby, edge-on galaxy NGC 4565 in the Beijing-Arizona-Taipei-Connecticut (BATC) 6660A band using the large-format CCD system on the 0.6m S…
Spatially resolved Spectro-photometry of M81: Age, Metallicity and Reddening Maps
X. Kong, X. Zhou, J. S. Chen +1
In this paper, we present a multi-color photometric study of the nearby spiral galaxy M81, using images obtained with the Beijing Astronomical Observatory 60/90 cm Schmidt Telescop…
Asteroseismological Observations of the Central Star of the Planetary Nebula NGC 1501
H. E. Bond, S. Kawaler, R. Ciardullo +17
We report on a global CCD time-series photometric campaign to decode the pulsations of the nucleus of the planetary nebula NGC1501. The star is hot and hydrogen-deficient, similar…
Deep Wide-Field Spectrophotometry of the Open Cluster M67
Xiaohui Fan, David Burstein, Jian-sheng Chen +21
We present nine color CCD intermediate-band spectrophotometry of a two square degree field centered on the old open cluster M67, from 3890 to nearly 1. These observations…
