Description
The Microlensing Observations in Astrophysics (MOA) collaboration is an international research project that uses gravitational microlensing for the discovery of exoplanets. MOA was initiated in the late 1990s and primarily involves institutions from Japan and New Zealand. The collaboration's observation site is the Mount John Observatory in New Zealand. We present here an overview of the MOA collaboration data archive, in terms of the monthly and annual number of images taken towards the MOA fields in the Galactic bulge and Magellanic Cloud regions, exposure times, the time between observations, and the monthly altitude distribution of observations (Reasonable requests for MOA data will be considered by the MOA collaboration. Primary contacts for data requests are Preeti Cowan (preeti.cowan [at] auckland.ac.nz (preeti[dot]cowan[at]auckland[dot]ac[dot]nz)) and Nicholas Rattenbury (n.rattenbury [at] auckland.ac.nz (n[dot]rattenbury[at]auckland[dot]ac[dot]nz))).

    LUMINARIES IN THE SKY: THE TESS LEGACY SAMPLE OF BRIGHT STARS. II. In depth seismic characterisation of the 34 luminaries found in the PLATO LOP fields
    The Transiting Exoplanet Survey Satellite (TESS; Ricker et al. 2024) is conducting a nearly full-sky survey, enabling the photometric characterisation of millions of stars. Lund et al. (sub) define a catalog of 196 bright stars ─ referred to as the Luminaries ─ that exhibit solar-like oscillations. These stars serve as important calibrators for

    Characterising six solar analogues observed by Kepler, K2, and Hermes
    The Sun is a cornerstone of stellar astrophysics, offering a uniquely detailed benchmark due to its proximity. However, our ability to observe it spans only a brief window of its 4.5-billion-year evolution, raising the question: how typical is the Sun among solar-type stars? This has led to the identification of solar twins—stars nearly identical

    Finding the sweet spot: Modelling of oscillating red giant binaries
    Binary stars are essential astrophysical test-beds. As the components of binary systems are formed from the same material and at the same time, they share fundamental properties such as their age and initial composition. Among the different types of binary systems, eclipsing binaries give the most stringent constraints about the stars, such as the
