The revised orbit of the {delta} Sco system
In anticipation of the possible collision between a circumstellar disk and the secondary star in the highly eccentric binary system {delta} Scorpii, high angular resolution... -
1.3mm VLBI observations of Sagittarius A*
Sagittarius A, the ~4x10^6^M_{sun}_ black hole candidate at the Galactic center, can be studied on Schwarzschild radius scales with (sub)millimeter wavelength very long baseline... -
DISCS. I. Taurus protoplanetary disk data
Chemistry plays an important role in the structure and evolution of protoplanetary disks, with implications for the composition of comets and planets. This is the first of a... -
31GHz sky survey with the SZA
We present the first sample of 31GHz selected sources to flux levels of 1mJy. From late 2005 to mid-2007, the Sunyaev-Zel'dovich Array observed 7.7deg^2^ of the sky at 31GHz to... -
Gravitational-wave bursts with GRBs
We present the results of a search for gravitational-wave bursts (GWBs) associated with 137 gamma-ray bursts (GRBs) that were detected by satellite-based gamma-ray experiments... -
Observation of Ser FIRS 1 at 230GHz
We present the first results of a program to characterize the disk and envelope structure of typical Class 0 protostars in nearby low-mass star-forming regions. We use Spitzer... -
Radio transients in a 1.4GHz drift-scan survey
We report two new radio transients at high Galactic latitude, WJN J0951+3300 (RA=09h51m22s+/-10s, DE=33{deg}00'+/-0.4{deg}, b=50{deg}54.2') and WJN J1039+3300... -
CH_3_OH maser survey of EGOs
We present the results of a high angular resolution Very Large Array (VLA) Class I 44GHz and Class II 6.7GHz CH_3_OH maser survey of a sample of ~20 massive young stellar object... -
Circumstellar disk of {chi} Oph
We present a numerical model describing a circularly symmetric gaseous disk around the Be star {chi} Ophiuchi. The model is constrained by long-baseline interferometric... -
CHARA observations of 3 late-type stars
Using the longest baselines of the CHARA Array, we have measured the angular diameter of the G5V subdwarf {mu} Cas A, the first such determination for a halo population star. We... -
Diameters of exoplanet host stars
We have measured the angular diameters for a sample of 24 exoplanet host stars using Georgia State University's CHARA Array interferometer. We use these improved angular... -
PISCO speckle observations in 2006
We present relative astrometric measurements of visual binaries made during the second semester of 2006, with the speckle camera PISCO at the 102cm Zeiss telescope of Brera... -
Resolved binary stars in Pleiades
The Pleiades is the most prominent open star cluster visible from Earth and an important benchmark for simple stellar populations unified by common origin, age, and distance.... -
Speckle interferometry at SOAR telescope in 2023
Results of the speckle-interferometry observations at the 4.1m Southern Astrophysical Research Telescope obtained during 2023 are presented: 1913 measurements of 1533 resolved... -
Binary stars: visual orbits & interferometry
Knowledge of the orbits of visual binary stars has always been one of the fundamentals of astronomy. Based historically on the visual measures, nowadays the orbits rely more (or... -
Correspondence TOIs & TESS control stars
The large number of exoplanets discovered with the Transiting Exoplanet Survey Satellite (TESS) means that any observational biases from TESS could influence the derived stellar... -
MeerKAT calibrator sources polarization properties
We report on full-Stokes L-band observations of 98 MeerKAT calibration sources. Linear polarization is detected in 71 objects above a fractional level of 0.2%. We identify ten... -
Observations with DSSI. XI. APO binaries measures
The Differential Speckle Survey Instrument (DSSI) was relocated to the Astrophysical Research Consortium 3.5m telescope at Apache Point Observatory (APO) in early 2022. Here we... -
2022 SOAR speckle interferometry of double stars
Results of the speckle-interferometry observations at the 4.1m SOuthern Astrophysical Research Telescope obtained during 2022 are presented: 2508 measurements of 1925 resolved... -
Speckle observations TESS exoplanet host stars. II.
We present high-angular-resolution imaging observations of 517 host stars of TESS exoplanet candidates using the 'Alopeke and Zorro speckle cameras at Gemini North and South....
