Herbig Ae/Be stars are young, pre-main-sequence stars that provide critical insights into the processes of stellar formation, early stellar evolution and protoplanetary disks....

At the end of their lives, when low- to intermediate-mass stars reach the asymptotic giant branch (AGB), their photosphere expands up to a few hundred times and a strong stellar...

An optical polarimetric catalog for the Small Magelanic Cloud (SMC) is presented. It gives intrinsic and observed polarizations in the V-band for a total of 7207 stars located...

A public database composed of real-world color polarimetric images of the sky in various weather condition over a month (~ 08-2022) in La Timone, Marseille More information in...

RX J1604 is a dipper source, and the data show different kinds of variability. However, a detailed analysis of repeated measurements shows that the results are not affected by...

Magnetic fields pervade the interstellar medium (ISM), but are difficult to detect and characterize. The new generation of low-frequency radio telescopes, such as the Low...

One clear manifestation of dynamo action on the Sun is the 22-yr magnetic cycle, exhibiting a polarity reversal and a periodic conversion between poloidal and toroidal fields....

We present an optical polarimetry study of the nearby star-forming region Lambda-Orionis to map the plane-of-the-sky magnetic field geometry to understand the magnetized...

PolarBase is an evolving data base that contains all stellar data collected with the ESPaDOnS and NARVAL high-resolution spectropolarimeters, in their reduced form, as soon as...

This preliminary version of Bibliographic Catalogue of Stellar Polarization (BCSP) contains data about polarization measurements of more than 1600 galactic objects published...

The catalogue contains observations of the linear polarization in the UBVRI photometric system of 8 Northern Be stars; the observations are part of a long-term monitoring...

We present an agglomeration of stellar polarization catalogs with results for 9286 stars. We have endeavoured to eliminate errors, provide accurate positions, sensibly weight...

Polarization data are given for stars whose polarizations are mostly interstellar which were observed for various programs with the University of Wisconsin spectropolarimeter...

The catalogue is an extension of the catalogue compiled by Mathewson and Ford (1970MmRAS..74..139M) and the list by Klare and Neckel (1977A&AS...27..215K). Cone search...

We have undertaken a comprehensive search for 5 cm OH masers in regions visible from Effelsberg with the 100-m telescope (i.e., those with declinations above -29^o^). Our sample...

The results of coordinated Crimea-Dodaira simultaneous multi-bands photometric and polarimetric observations of the classical Herbig Ae/Be star RR Tau which cover fully the...

The table contains optical polarization data for a sample of 170 moderate to high-redshift quasars

Asteroids are used as far-IR calibrators for the imaging photopolarimeter ISOPHOT on board the Infrared Space Observatory ISO. For the 10 selected objects we compiled a large...

Table 2 contains optical (V) polarimetric measurements for 42 optically selected QSOs including 29 broad absorption line QSOs. Table 3 contains a series of spectral indices...

The T Tauri star RY Tau has increased its brightness from V=10.6mag to V=9.6mag in October-November 1996. By February-March 1997, the star has faded again to V=10.8mag....
