K2-25: An eccentric hot Neptune with the mass of seven Earths

Of the roughly 4,300 exoplanets confirmed to date, about ten percent of them are classified as "hot Jupiters." These are planets with masses between about 0.4 and 12 Jupiter-masses and orbital periods less than about 110 ...

Researchers identify periods in asynchronous polars

A polar is a highly magnetic type of cataclysmic variables containing an accreting white dwarf and a low-mass donor star. Due to the magnetism, the white dwarf would synchronously spin, however, there are still several asynchronous ...

Most eccentric known M-dwarf binary system discovered

An international team of astronomers has discovered a new M-dwarf binary system as part of the Next Generation Transit Survey (NGTS). The newly found system, designated NGTS J214358.5-380102, turns out to be the most eccentric ...

New binary millisecond pulsar discovered in NGC 6205

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have detected a new binary millisecond pulsar (MSP) in the globular cluster NGC 6205. The newly found pulsar received designation PSR J1641+3627F. ...

Deep eclipses detected in the cataclysmic variable J0130

Russian astronomer Valery Kozhevnikov has conducted photometric observations of the cataclysmic variable (CV) IPHAS J013031.89+622132.3 (J0130 for short), finding that the object exhibits deep eclipses. The discovery, presented ...

New 'warm Jupiter' exoplanet discovered

An international team of astronomers reports the discovery of a new "warm Jupiter" alien world transiting a main sequence late F-type star on an eccentric orbit. The newfound exoplanet, designated TOI-677 b, is about 20 percent ...
