    New IRIS constraints on the solar core rotation.
    Four time series of IRIS data (4 to 6 months) have been used to obtain improved measurements of the low degree (l=1,2,3) rotational splitting frequencies...
  • Publication
    New Isolated Planetary-mass Objects and the Stellar and Substellar Mass Function of the σ Orionis Cluster
    We report on our analysis of the VISTA Orion ZY JHKs photometric data (completeness magnitudes of Z = 22.6 and J = 21.0 mag) focusing on a circular area of 2798...

    New Light and Shadows on Stephan's Quintet
    We present deep broadband R and narrowband Hα images of Stephan's Quintet. The observations in the R band show that the diffuse halo of Stephan's Quintet is...

    New Light in Star-Forming Dwarf Galaxies: The PMAS Integral Field View of the Blue Compact Dwarf Galaxy Mrk 409
    We present an integral field spectroscopic study of the central 2 × 2 kpc2 of the blue compact dwarf galaxy Mrk 409, observed with the Potsdam MultiAperture...
  • Publication
    New Light on an Old Problem of the Cores of Solar Resonance Lines
    We reexamine a 50+ yr old problem of deep central reversals predicted for strong solar spectral lines, in contrast to the smaller reversals seen in observations...
  • Publication
    New limits on the cosmic microwave background fluctuations on a 5° angular scale.
    The authors describe their new observations on scales of 5° - 12° and comment on their significance for various scenarios of galaxy formation.
  • Publication
    New Mass and Radius Constraints on the LHS 1140 Planets: LHS 1140 b Is either a Temperate Mini-Neptune or a Water World
    The two-planet transiting system LHS 1140 has been extensively observed since its discovery in 2017, notably with Spitzer, HST, TESS, and ESPRESSO, placing...

    New massive members of Cygnus OB2
    Context. The Cygnus complex is one of the most powerful star forming regions at a close distance from the Sun ( 1.4 kpc). Its richest OB association Cygnus OB2...
  • Publication
    New measurement of the 6Li/7Li isotopic ratio in the extra-solar planet host star HD 82943 and line blending in the Li 6708 Å region
    The presence of possible blends in the spectral region of the Li resonance line at 6708 Å in solar-type metal-rich stars is investigated using high resolution...
