  • Chemical abundances in 31 stars with planet

    We present the results of detailed spectroscopic abundance analyses for 18 elements in 31 nearby stars with planets (SWPs). The resulting abundances are combined with other...
  • SuperWASP exoplanetary transit survey

    Photometric transit surveys promise to complement the currently known sample of extra-solar planets (ESPs) by providing additional information on the planets and especially...
  • Abundance distribution of stars with planets

    We present the results of a uniform, high-precision spectroscopic metallicity study of 136 G-type stars from the Anglo-Australian Planet Search, 20 of which are known to harbour...
  • Abundances in solar atmosphere

    An analysis of the chemical composition of the solar atmosphere is performed using spectrograms of the daylight sky obtained on the ZTS telescope (dispersion 3{AA}/mm,...
  • FOSSIL. III. LCs of Trans-Neptunian Objects

    From the first phase of the high-cadence Formation of the Outer Solar System: an Icy Legacy (FOSSIL) survey, we analyzed lightcurves, ranging from one to four nights in length,...
  • In the Trenches of the solar-stellar connection. VII.

    The Wilson-Bappu effect (WBE) is a remarkable correlation between the width of the chromospheric emission core of the CaII 3934{AA} K line and stellar absolute visual magnitude...
  • TNOs mean-motion resonances with Neptune

    In this paper, we present a large-scale dynamical survey of the trans- Neptunian region, with particular attention to mean-motion resonances (MMRs). We study a set of 4121...
  • ^3^He-rich time periods 1997-2021 from ACE & STEREO

    Using ion measurements from Ultra-Low-Energy Isotope Spectrometer observations on board Advanced Composition Explorer and Solar Isotope Spectrometer observations on board the...
  • Cassini Visual & IR obs. of Saturn & Jupiter

    With the advent of direct-imaging spectroscopy, the number of spectra from brown dwarfs and extrasolar gas giants is growing rapidly. Many brown dwarfs and extrasolar gas giants...
  • FOSSIL. II. Subaru/HSC light curves of Hildas

    Using the high-cadence lightcurves collected from the FOSSIL survey, rotation periods of 17 small (diameter 1km<D<3km) Hilda asteroids (hereinafter Hildas) were obtained....
  • TNOs from the full six years of DES

    We present a search for outer solar system objects in the 6yr of data from the Dark Energy Survey (DES). The DES covered a contiguous 5000deg^2^ of the southern sky with ~80000...
  • SCO daily sunspot area measurements (1886-1940)

    A sunspot observation program was started at the end of the 19th century at the Stonyhurst College Observatory (hereafter SCO) by Father Perry, director of the observatory at...
  • The Fermi-LAT long-term transient sources (1FLT)

    We present the first Fermi Large Area Telescope (LAT) catalog of long-term {gamma}-ray transient sources (1FLT). This comprises sources that were detected on monthly time...
  • Rotation periods from the K2 Campaign 9

    The Kepler mission is a powerful tool for the study of different types of astrophysical objects or events in the distant universe. However, the spacecraft also provides an...
  • Quiet-Sun MgII h & k line profiles from IRIS

    We derived high-precision reference profiles of the MgII h and k lines that represent the quiet Sun during a minimum of the solar activity. To do so, we used the broad catalog...
  • Kepler light curves of Jovian Trojan asteroids

    Various properties of Jovian Trojan asteroids such as composition, rotation periods, and photometric amplitudes, or the rate of binarity in the population, can provide...
  • Nitrogen isotopic compositions in Isheyevo

    We report on the discovery of 33 oxygen-anomalous grains from the CH3/CB_b_3 chondrite Isheyevo and the CR2 chondrite Northwest Africa (NWA) 801. Oxygen isotopic compositions...
  • Solar flare variability from GOES-15 Ly{alpha} obs.

    The Lyman-alpha (Ly{alpha}) line of neutral hydrogen at 121.6nm is by far the brightest emission line in the vacuum ultraviolet spectral range of the Sun. The emission at this...
  • ATLAS c-o colors and classification of asteroids

    We present here the c-o colors for identified Flora, Vesta, Nysa-Polana, Themis, and Koronis family members within the historic data set (2015-2018) of the Asteroid...
  • OSSOS. XII. Subaru/HSC obs. of 65 TNOs

    We present variability measurements and partial light curves of trans-Neptunian objects (TNOs) from a two-night pilot study using Hyper Suprime-Cam (HSC) on the Subaru Telescope...
