We present an analysis of the young stellar moving group ASCC 127 using Gaia DR3 data, significantly expanding its membership to 3971 stars-double the number identified in...

We examine the H I gas kinematics of galaxy pairs in two clusters and a group using Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pilot survey observations. We...

Massive stars play crucial roles in galactic dynamics and chemical evolution. They are the most significant sources of ionizing UV radiation, their substantial mass-loss rates...

Using the Five-hundred-meter Aperture Spherical radio Telescope, we have performed an Ursa Major supergroup HI survey covering the entire UMa region centered at...

We use accurate absolute UCAC4 proper motions, V-band photoelectric and CCD photometry including our own and compiled data, WISE W1-band mid-IR photometry, as well as extensive...

We present 21-cm observations of a 10x2deg^2^ region in the Virgo cluster, obtained as part of the Arecibo Galaxy Environment Survey. 289 sources are detected over the full...

We report the confirmation of three transiting exoplanets orbiting TOI-1243 (LSPM J0902+7138), TOI-4529 (G 2-21) and TOI-5388 (Wolf 346) initially detected by TESS, through...

The accretion of Gaia-Enceladus/Sausage (GES) onto the Milky Way is one of the most prominent features of the Galactic halo revealed by the combination of the Gaia satellite and...

Three-body interactions can eject stars from the core of a globular cluster, causing them to enter the Galactic halo as extra-tidal stars. While finding extra-tidal stars is...

Gas giant planets orbiting low-mass stars (Teff<=4600K) are uncommon outcomes of planet formation. Increasing the sample of well-characterised giants around early M dwarfs...

Sub-Neptunes with planetary radii of R_p_=~2-4 R_{Earth} are the most common planets around solar-type stars in short-period (P<100d) orbits. It is still unclear, however,...

The CARMENES instrument, installed at the 3.5 m telescope of the Calar Alto Observatory in Almería, Spain, was conceived to deliver high-accuracy radial velocity (RV)...

Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such...

The HARPS-N solar telescope has been observing the Sun every possible day since the summer of 2015. We recently released 10 years of these data, which are available online.The...

The solar neighbourhood is populated by nearby (<200pc), young (<100Myr) moving groups (NYMGs) of stars, whose origins are still debated. A possible explanation is that...

The outer Galactic halo remains relatively unexplored, particularly regarding its metallicity distribution, merger debris, and the population of very and extremely metal-poor...

The Canis Major (CMa) star-forming region, a remote molecular cloud complex within the recently discovered Radcliffe Wave, remains underexplored in literature. We revisit the...

GJ 877 is a bright M dwarf in the solar neighborhood with two currently reported nontransiting exoplanets with periods of 9d and 21d, along with an additional unconfirmed signal...

The transition regime between giant planets (GPs) and brown dwarfs (BDs) is still an open subject of study in exoplanetary science. A complete understanding of the population of...
