  • V4141 Sgr: Outflows and repeated outbursts
    In this work, we analyze the ongoing brightening of the poorly studied symbiotic star V4141 Sgr and examine its long-term variability. We present new low-resolution spectroscopic observations of the system in its bright state and combine them with multi-color photometric data from our observations, as well as ASAS-SN, ATLAS, and Gaia DR3. To

  • Transverse oscillations in 3D along Ca II K bright fibrils in the solar chromosphere
    Context. Fibrils in the solar chromosphere carry transverse oscillations as determined from non-spectroscopic imaging data. They are estimated to carry an energy flux of several kW m ‑2, which is a significant fraction of the average chromospheric radiative energy losses. Aims. We aim to determine the oscillation properties of fibrils not only in

  • TOI-6478 b: a cold underdense Neptune transiting a fully convective M dwarf from the thick disc
    Growing numbers of exoplanet detections continue to reveal the diverse nature of planetary systems. Planet formation around late-type M dwarfs is of particular interest. These systems provide practical laboratories to measure exoplanet occurrence rates for M dwarfs, thus testing how the outcomes of planet formation scale with host mass, and how

  • Tidally Heated Sub-Neptunes, Refined Planetary Compositions, and Confirmation of a Third Planet in the TOI-1266 System
    TOI-1266 is a benchmark system of two temperate (<450 K) sub-Neptune-sized planets orbiting a nearby M dwarf exhibiting a rare inverted architecture with a larger interior planet. In this study, we characterize transit timing variations (TTVs) in the TOI-1266 system using high-precision ground-based follow-up and new TESS data. We confirm the

  • The TOI-700 System at 5 Years: New Radial Velocity Mass Measurements and Updated Transit Fits
    The TOI-700 system was discovered in 2020 using data from NASA's TESS mission. At that time, there were three known planets, including TOI-700 d, the first Habitable Zone planet from TESS. In 2023, a fourth planet was discovered in the system, TOI-700 e, orbiting in the stars Optimistic Habitable Zone. Now, five years after its initial discovery

  • The Rise of Faint, Red Active Galactic Nuclei at z &gt; 4: A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields
    We present a sample of 341 "little red dots" (LRDs) spanning the redshift range z ∼ 2–11 using data from the CEERS, PRIMER, JADES, UNCOVER, and NGDEEP surveys. Unlike past use of color indices to identify LRDs, we employ continuum slope fitting using shifting bandpasses to sample the same rest-frame emission blueward and redward of the Balmer break
