  • Compilation of double radio sources

    The origin of magnetic fields in clusters of galaxies is still a matter of debate. Observations for intracluster magnetic fields over a wide range of redshifts are crucial to...
  • ICMEs observed by Juno between 1 and 5.4au

    We use magnetic field measurements by the Juno spacecraft to catalog and investigate interplanetary coronal mass ejections (ICMEs) beyond 1au. During its cruise phase, Juno...
  • IGRINS YSO survey. I. PMS stars in Tau-Aur

    We present fundamental parameters for 110 canonical K- and M-type (1.3-0.13M_{sun}_) Taurus-Auriga young stellar objects (YSOs). The analysis produces a simultaneous...
  • Reconstruction of solar irradiance from 1700 to 2019

    We model the Sun's large-scale magnetic field and total solar irradiance (TSI) since 1700 by combining flux transport simulations with empirical relationships between facular...
  • Stellar polarimetry with Gaia DR2 data

    Optical stellar polarimetry in the Perseus molecular cloud direction is known to show a fully mixed bimodal distribution of position angles across the cloud. We study the Gaia...
  • Starspots's temperature and area in 337 KIC stars

    Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type...
  • MHD simulations cases; Martian bow shock model

    Using global MHD simulations, we construct a 3D parametric Martian bow shock model that employs a generalized conic section function defined by seven parameters. Effects of the...
  • Proton synchrotron gamma-rays in blazars

    The origin of high-energy emission in blazars jets (i.e., leptonic versus hadronic) has been a longstanding matter of debate. Here, we focus on one variant of hadronic models...
  • Single storms and the related ICMEs from 1998-2011

    Interplanetary coronal mass ejections (ICMEs) could be classified into magnetic clouds (MCs) and non-MCs according to their magnetic field signatures, and into prominence-inside...
  • Faraday rotation of radio sources from THOR

    We present first results for Faraday rotation of compact polarized sources (1-2GHz continuum) in The HI/OH/Recombination line (THOR) survey of the inner Galaxy. In the Galactic...
  • Global energetics of solar flares. IX.

    A more accurate analytical solution of the vertical-current approximation nonlinear force-free field (VCA3-NLFFF) model is presented that includes, besides the radial (Br) and...
  • BAT AGN spectroscopic survey. XVI. Blazars

    The recently released 105-month Swift-Burst Alert Telescope (BAT) all-sky hard X-ray survey catalog presents an opportunity to study astrophysical objects detected in the...
  • Magnetic field measurements of Ap/Bp stars

    We report on magnetic field measurements of 157 chemically peculiar A/B stars (Ap/Bp) based on resolved, magnetically split absorption lines present in H-band spectra provided...
  • JVLA rotation measures of Smith cloud bckg sources

    The Smith Cloud is a high-velocity cloud with an orbit suggesting it has made at least one passage through the Milky Way disk. A magnetic field found around this cloud has been...
  • Spot parameters on KIC solar-type stars

    Active solar-type stars show large quasi-periodic brightness variations caused by stellar rotation with star spots, and the amplitude changes as the spots emerge and decay. The...
  • Magnetohydrodynamic (MHD) simulations. II.

    During the lifetime of Sun-like or low-mass stars a significant amount of angular momentum is removed through magnetized stellar winds. This process is often assumed to be...
  • Statistical studies of solar white-light flares

    Recently, many superflares on solar-type stars have been discovered as white- light flares (WLFs). The statistical study found a correlation between their energies (E) and...
  • ALMA obs. of polarized dust emission from Ser-emb 8

    We report Atacama Large Millimeter/submillimeter Array (ALMA) observations of polarized dust emission from the protostellar source Ser-emb 8 at a linear resolution of 140au....
  • Periodicity & magnitude of Kepler LCs variation

    The variation of a stellar light curve owing to rotational modulation by magnetic features (starspots and faculae) on the star's surface can be used to investigate the magnetic...
  • Spectropolarimetric survey of radio sources

    We present a broadband spectropolarimetric survey of 563 discrete, mostly unresolved radio sources between 1.3 and 2.0 GHz using data taken with the Australia Telescope Compact...
