PHOEBE (PHysics Of Eclipsing BinariEs) is a modeling package for eclipsing binary stars, built on top of the widely used WD program (Wilson & Devinney 1971). This introductory paper overviews most important scientific extensions (incorporating observational spectra of eclipsing binaries into the solution-seeking process, extracting individual temperatures from observed color indices, main-sequence constraining and proper treatment of the reddening), numerical innovations (suggested improvements to WD's Differential Corrections method, the new Nelder & Mead's downhill Simplex method) and technical aspects (back-end scripter structure, graphical user interface). While PHOEBE retains 100% WD compatibility, its add-ons are a powerful way to enhance WD by encompassing even more physics and solution reliability. The operability of all these extensions is demonstrated on a synthetic main-sequence test binary; applications to real data will be published in follow-up papers. PHOEBE is released under the GNU General Public License, which guarranties it to be free, open to anyone interested to join in on future development.

  1. A Galactic intermediate-mass stripped star with a Wolf-Rayet-like wind

    astro-ph.SR 2026-08 conditional novelty 7.0 of 10

    WR 2-1 is the first unambiguous intermediate-mass stripped star in the Milky Way: a 3-6 solar mass, 60 kK helium-rich companion in a 5.94-day binary with a rapidly rotating O-star.

  2. Astronomical Cardiology II: A Search For Heartbeat Stars Using APOGEE and TESS

    astro-ph.SR 2026-08 conditional novelty 6.0 of 10

    A new search of APOGEE binaries with TESS light curves finds 50 heartbeat stars, including 36 new systems, and confirms that the detected fraction rises sharply with stellar temperature.

  3. A new likely pulsar binary in 47~Tucanae from continuum searches

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    47 Tuc W41 is a redback millisecond-pulsar binary with Lx ~ 3e31 erg/s, steep-spectrum radio continuum, and an irradiated ~0.5 Msun secondary on a 10.4-hr orbit.

  4. The forgotten bright star: Theta Eridani as a millenary stellar transient observed by Hipparchus, Ptolemy and al-Sufi

    astro-ph.SR 2026-06 unverdicted novelty 6.0 of 10

    Theta Eridani's historical brightness is explained as a millenary common-envelope transient powered by orbital energy extraction in a previously more eccentric binary.

  5. TESS light curves and surface activity in two low-mass eclipsing binaries: NSVS 01031772 and 2MASS J04100497+2931023

    astro-ph.SR 2026-07 conditional novelty 4.0 of 10

    TESS and ground-based photometry of two low-mass eclipsing binaries yield improved stellar parameters, evidence for tertiary companions via the light-time effect, and a flare frequency of one per 40 hours for NSVS 01031772.
