Highly collimated bipolar outflows have been detected in the planetary nebula NGC 6572 via ground-based optical imagery and high-resolution long-slit...

Context. Determining empirical atmospheric models for the solar chromosphere is difficult since it requires the observation and analysis of spectral lines that...

We present deep V, R, and I broadband CCD images of the northern radio lobe associated with the radio galaxy 3C 390.3. Spatially resolved emission coincident...

A recent report on the detection of very-high-energy gamma rays from V4641 Sagittarii (V4641 Sgr) up to ≈0.8 PeV has made it the second confirmed "PeVatron"...

Context. Studies of the magnetic characteristics of massive stars have recently received significant attention because they are progenitors of highly magnetised...

Context. Theoretical studies predict the presence of thermal inversions in the atmosphere of highly irradiated gas giant planets. Recent observations have...

Ultrahot Jupiters are a type of gaseous exoplanet that orbit extremely close to their host star, resulting in significantly high equilibrium temperatures. In...

Ultra-hot Jupiters are gas giants planets whose dayside temperature is greater than 2200 K as a consequence of the strong irradiation received from the host...

Stellar flares are characterized by sudden enhancement of electromagnetic radiation from the atmospheres of stars. Compared to their solar counterparts, our...
