Description
Two interesting case studies of pulsating components in triple systems are highlighted in this presentation. We first report on the new results of a detailed study of the double-lined spectroscopic-visual system DG Leonis based on recent photometric and high-resolution spectroscopic data. This triple system has two components showing mild Am abundance peculiarities and at least one pulsating component of the type δ Scuti. In the second case we report on the new results obtained for the single-lined spectroscopic-visual triple system λ Scorpii. A careful spectroscopic analysis allowed to detect the presence of four pulsation frequencies, the most dominant of which was shown to be subject to the light-time effect. None of these frequencies are likely to be excited by tidal interaction.

    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

    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

    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
