    On the nature of HD 207331: a new δ Scuti variable
    While testing a Strömgren spectrophotometer attached to the 1.5 m telescope at the San Pedro Mártir observatory, Mexico, a number of A-type stars were observed...

    On the nature of Hα emitters at z ˜ 2 from the HiZELS survey: physical properties, Lyα escape fraction and main sequence
    We present a detailed multiwavelength study (from rest-frame ultraviolet to far-infrared) of narrow-band selected, star-forming (SF) Hα emitters (HAEs) at z ˜ 2...

    On the nature of kink MHD waves in magnetic flux tubes
    Context: Magnetohydrodynamic (MHD) waves are often reported in the solar atmosphere and usually classified as slow, fast, or Alfvén. The possibility that these...

    On the nature of lithium-rich giant stars. Constraints from beryllium abundances
    We have derived beryllium abundances for 7 Li-rich giant (A(Li) > 1.5) stars and 10 other Li-normal giants with the aim of investigating the origin of the...

    On the nature of the current GOLF p-mode signal
    The GOLF experiment on board SOHO is designed to measure global oscillations of the disk-integrated sunlight with high sensitivity and with long term stability...

    On the nature of the extragalactic number counts in the K-band
    Context: The galaxy number counts has been traditionally used to test models of galaxy evolution. However, the origin of significant differences in the shape of...

    On the nature of the most obscured C-rich AGB stars in the Magellanic Clouds
    The stars in the Magellanic Clouds with the largest degree of obscuration are used to probe the highly uncertain physics of stars in the asymptotic giant branch...

    On the nature of the photometric variability of the luminous blue variable P Cygni.
    P Cygni is one of the most luminous variable stars in our Galaxy. It is the only luminous blue variable which does not show photometric variability on a scale...

    On the nature of the red, 2MASS-selected AGN in the local Universe I: an optical spectroscopic study
    We present optical spectra for a representative sample of 27 nearby (z 0.2) Two Micron All Sky Survey (2MASS)-selected active galactic nuclei (AGN) with red...
