Descripción
The interaction between plasma flow and magnetic field transports magnetic energy and helicity through the photosphere. It plays an important role in driving the dynamics in the solar atmosphere. In my talk, I will first show the application of a newly developed flow tracking method, DAVE4VMwDV, in studying the field-aligned flow near the polarity inversion line of active region 12673. I will discuss the possible reasons for the discrepancies in estimating the Poynting flux and helicity flux with different flow-tracking and electric field inversion methods, and show that the design philosophy and ad hoc treatments of the Doppler and transverse velocity are responsible for the discrepancies. In addition, I will show the potential of DKIST in studying the quiet Sun flow field and energy transport. Finally, I will discuss the implications for the improvement of flow tracking methods.

    A new perspective on the solar tachocline from long and very long time-series.
    With some 15, 15 and 30 years of MDI, HMI and GONG observations, respectively, we have reached a new milestone in acquiring almost three decades of nearly continuous helioseismic observations. Moreover, an alternative fitting methodology for global helioseismology to the respective projects' pipeline has produced tables of individual mode

    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

    Accretion Diagnostics for JWST–MIRI: Establishing the Relationship between Mid-Infrared Hydrogen Lines and the Accretion Luminosity
    We have established mid-infrared hydrogen recombination lines observed with JWST as accretion tracers for pre-main-sequence stars that accrete from circumstellar disks. These new relations equip the community with a direct measurement of the accretion luminosity from MIRI-MRS spectra. A MIRI-derived accretion luminosity is fundamental for time
