Speckle interferometry at USNO. II.
Position angles and separations resulting from 2406 speckle interferometric observations of 547 binary stars are tabulated. This is the second in a series of papers presenting... -
ICCD Speckle obs. of binary stars. XIII
Nine hundred eighty-nine observations of 694 binary star systems, observed by means of speckle interferometry with the 4m telescope on Cerro Tololo, are presented. Included in... -
Speckle observations of binary stars. XII
Five hundred sixty-five measurements of 99 binary star systems are presented, obtained during 1984-1986 by means of speckle interferometry at the 1.8 m Perkins telescope on... -
Orbits of 37 close visual systems
New orbital elements are presented for 37 close visual systems that have been observed and in some cases discovered by speckle interferometry. Periods of these systems range... -
ICCD speckle observations of binary stars. XI.
One-thousand one-hundred ninety-seven observations of 730 binary star systems, observed by means of speckle interferometry with the 4m telescope on Kitt Peak, are presented.... -
ICCD speckle observations. IX
Multiplicity of stars within clusters is a well-studied phenomenon. However, recent survey work done on the Hyades by Mason et al. [1993AJ....105..220M] would seem to indicate... -
Speckle observations of binary stars VIII
One-thousand eighty-eight observations of 947 binary star systems, observed by means of speckle interferometry with the 4 m telescope on Cerro Tololo, are presented. These... -
Speckle observations of binary stars
Speckle interferometric observations from the Canada-France-Hawaii 3.6m and Cerro Tololo 4 m telescopes are reported for 1123 stars selected from the Yale Bright Star Catalogue... -
MeerKAT Absorption Line Survey (MALS). DR3
We present results of a blind search for Galactic HI 21-cm absorption lines toward 19130 radio sources, using 390 pointings of MALS, each pointing centered on a source brighter... -
ALMAGAL III. Compact source catalog
The physical mechanisms behind the fragmentation of high-mass dense clumps into compact star-forming cores and the properties of these cores are fundamental topics that are... -
ALMAGAL. I. Target clumps properties
A large fraction of stars form in clusters containing high-mass stars, which subsequently influences the local and galaxy-wide environment. Fundamental questions about the... -
VLTI/GRAVITY limit on Gaia BH3 emission
The recent astrometric discovery of the nearby (590pc), massive (33M_{sun}) dormant black hole candidate Gaia BH3 offers the possibility to resolve angularly the black hole from... -
Newborn Be star system
Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been... -
Millimetre observations of chi Cygni
New observations are presented of millimetre line emissions of the circumstellar envelope (CSE) of the asymptotic giant branch (AGB) star chi Cygni, using the recently upgraded... -
LOFAR ELAIS-N1 field at 144MHz catalog
We present the first wide area (2.5x2.5deg^2^) LOFAR High Band Antenna image at a resolution of 1.2arcsecx2arcsec with a median noise of approximately 80 microJy per beam. It... -
GRB 221009A afterglow reduced visibilities
We observed gamma-ray burst (GRB) 221009A using very long baseline interferometry (VLBI) with the European VLBI Network (EVN) and the Very Long Baseline Array VLBA), over a... -
M87 VLBA 43GHz images
Self-calibration methods with the CLEAN algorithm have been widely employed in Very Long Baseline Interferometry (VLBI) data processing in order to correct antenna-based... -
GLOSTAR GPS. X. Galactic HII region catalog
Studies of Galactic HII regions are of crucial importance for studying star formation and the evolution of the interstellar medium. Gaining an insight into their physical... -
GLOSTAR GPS. Radio source catalog
The GLObal view of the STAR formation in the Milky Way (GLOSTAR) survey studies star formation with the Very Large Array (VLA) and the Effelsberg 100 meter radio telescope in... -
Anatomy of L1489 IRS with NOEMA I
Over the past few years, chemical studies have revealed multiple structures in the vicinity of young stellar objects (YSOs). It has become evident that specific physical...
