Description
The authors have made observations of the spectrum of comet Halley on various dates between September 1985 and December 1986, obtaining multipositional long-slit absolute spectrophotometry of the inner region of the coma in the visible range. They present a study of the emission in the 3883 Å line of the (0-0) transition of CN. The observed CN surface brightness spatial distribution is used to obtain the distribution of molecules and is fitted to Haser's model to obtain scale lengths.

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging & Astronomy
    Diffuse emission in the outskirts of galaxies, such as stellar tidal streams, galaxy stellar halos and intracluster light, provides important constraints on the structure and evolution of the Universe. However, such low surface brightness diffuse emission can be up to thousands of times dimmer (>29 AB mag/[square arcseconds]) than the sky

    A Systematic Search for and Characterization of White Dwarf Binaries Across the H-R Diagram
    White dwarfs (WDs) are the endpoint of evolution for 97% of stars. Most of these stars are in multiple systems, and a significant fraction of those are compact enough to exchange mass, altering the structures and subsequent evolution of both stars. The physical mechanisms that facilitate these mass exchanges include common envelope evolution, Roche

    Deep HST Imaging Favors the Bulgeless Edge-on Galaxy Explanation for the Hypothetical Stellar Wake Created by a Runaway Supermassive Black Hole
    A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a bulgeless edge-on galaxy. We report on new very deep Hubble Space Telescope imaging that seems to be in tension with the SMBH runaway scenario but is consistent with the bulgeless edge-on
