Evolution of LMXBs under Different Magnetic Braking Prescriptions

MB plays a vital role in LMXB evolution; however, its mechanism has not been well understood. The traditional MB law faces difficulties in explaining the observational characteristics of LMXBs and MSPs, such as the discrepancy between th...

The Progress in Studies of Carbon-rich Type Ia supernova SN 2017hpa

Type Ia supernovae (SN Ia) are widely believed to originate from thermonuclear explosions of carbon-oxygen white dwarfs, and their essentially identical peak luminosities make them indicators of extra-galactic distances and important pro...

Extended HNCO, SiO, and HC3N Emission in 43 Southern Star-forming Regions

Shocks are a ubiquitous phenomenon in the interstellar medium (ISM) of galaxies. They may be driven by supernova explosions, the pressure of photoionized gas, stellar winds, and collisions between fast-moving clumps of interstellar gas, ...

Ammonia observations towards the Aquila Rift cloud complex

Ammonia (NH3) is frequently used as the standard molecular cloud thermometer (e.g., Ho & Townes 1983; Walmsley & Ungerechts 1983). NH3 (1,1) and (2,2), both belonging to the para-species of ammonia, have been proven to be an excellent th...

The Two Emission States of PSR B1534+12

PSR B1534+12 (J1537+1155) is a millisecond pulsar with a 37.9ms period in orbit with a neutron star companion with a 10.1 hr orbital period. This pulsar was discovered using the Arecibo 305 m radio telescope in the 430 MHz band. Timing a...

Evidence for Dense Gas heated by the Explosion in Orion KL

Orion Kleinmann-Low (Orion KL) nebula is the nearest massive star-forming region. An explosion occurred in this nebula about 550 years ago. The explosion not only accelerated several young stars, but also produced spectacular high veloci...
