Empirical 2MASS–WFC3/IR Filter Transformations Across the H-R Diagram from Synthetic Photometry
The Astronomical Journal, 2023 Near-infrared bandpasses on spaceborne observatories diverge from their ground-based counterparts as they are free of atmospheric telluric absorption.

Distances to Nearby Molecular Clouds Traced by Young Stars
The Astrophysical Journal Supplement Series, 2023 I present a catalog of distances to 63 molecular clouds located within ∼2.5 kpc of the Sun. The cloud distances are derived based on utilizing the Gaia DR3 parallaxes of the young stellar objects (YSOs). By identifying AllWISE YSO candidates (YSOCs) with

Stellar Distances and Hipparcos [PDF]
International Astronomical Union Colloquium, 1993 AbstractHipparcos, the astrometric satellite of the European Space Agency, launched in August 1989, will provide absolute trigonometric parallaxes for about 100 000 stars brighter than the limiting V-magnitude 12.5. In spite of the difficulties caused by a faulty orbit, the mission is successfully going on.

A New Wide-field Infrared Survey Explorer Calibration of Stellar Mass
The Astrophysical Journal, 2023 We derive new empirical scaling relations between Wide-field Infrared Survey Explorer (WISE) mid-IR (MIR) galaxy photometry and well-determined stellar masses from spectral energy distribution modeling of a suite of optical–infrared photometry provided ...

Stellar Distances by the Baade-Wesselink Method [PDF]
Symposium - International Astronomical Union, 1997 Galactic and extragalactic distances to Cepheid variable stars according to a modern realization of the geometric Baade-Wesselink method are presented. Reliable results as accurate as few percent are currently achievable, allowing the cosmic distance scale calibration to be significantly improved with respect to previous calibrations.

Disk accretion onto a magnetized star
EPJ Web of Conferences, 2014 The problem of interaction of the rotating magnetic field, frozen to a star, with a thin well conducting accretion disk is solved exactly. It is shown that a disk pushes the magnetic field lines towards a star, compressing the stellar dipole magnetic ...
