Using the Green Bank Telescope (GBT), astronomers from Columbia University and the University of California Berkeley have detected a new binary millisecond pulsar. The newly found pulsar, designated PSR J0212+5321, belongs ...
(Phys.org) —A trio of researchers from Germany, Bulgaria and Russia has proposed the idea of using a molecular clock to determine if the electron-proton mass ratio changes over time. In their paper published in Physical ...
Using the Guillermo Haro Observatory (OAGH) in Mexico, astronomers have performed spectroscopic observations of a dwarf nova known as U Geminorum. Results of the observational campaign, published March 10 on the arXiv pre-print ...
Using the Hubble Space Telescope (HST) and the Chandra X-ray Observatory, astronomers have taken a closer look at a short-period high-mass X-ray binary known as CXOU J121538.2+361921. Results of the observational campaign, ...
A research team led by Prof. Qian Shengbang and Ph.D. student Li Fuxing from the Yunnan Observatories of the Chinese Academy of Sciences has found that the formation and evolution of the massive binaries in the Milky Way ...

Using the Rozhen National Astronomical Observatory (NAO) in Bulgaria, astronomers have performed long-term monitoring of the quasar QSO B1312+7837 and have detected a periodic variability of this source. The finding is reported ...
Using the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), astronomers have discovered an unusual binary system. The newly found binary, designated LAMOST J0140355+392651 (or J0140 for short), consists ...
(Phys.org) —A research team led by FOM workgroup leader Prof. Dr. Wim Ubachs and Dr. Rick Bethlem has once again demonstrated that the mass ratio between electrons and protons has remained the same over the past 7.5 billion ...

Planets form as the dust grains in a protoplanetary disk grow into pebbles and then finally into planets. Because small dust grains interact with gas (via the drag it imparts), the gas in protoplanetary disks influences the ...
