The Hot, Continuum-compact State of the Yellow Hypergiant V509 Cassiopeiae: CHARA Diameters, CO-band Angular-extension Constraints, and Companion Limits

Narsireddy Anugu, Gail H. Schaefer, Douglas R. Gies +4

Yellow hypergiants are rare, evolved massive stars generally interpreted as post-red-supergiant objects evolving blueward through or near the dynamically unstable Yellow Evolutiona…

A decade of radial-velocity monitoring of rho Leo: moment analysis and periodic variability

V. A. Checha, A. Aret, I. Kolka +6

We investigate the origin of long-term spectroscopic and photometric variability in the blue supergiant rho Leo, with particular emphasis on distinguishing between intrinsic pulsat…

The Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES) Data Reduction Pipeline

Sandipan P. D. Borthakur, Tõnis Eenmäe, Nikolai Piskunov +9

We introduce the data reduction pipeline for the Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES). TOFES is installed in the Coudé room and will be connected to the 1.5 m T…

The IXPE view of GRB 221009A

Michela Negro, Niccoló Di Lalla, Nicola Omodei +108

We present the IXPE observation of GRB 221009A which includes upper limits on the linear polarization degree of both prompt and afterglow emission in the soft X-ray energy band. GR…

(3200) Phaethon Polarimetry in the Negative Branch: New Evidence for the Anhydrous Nature of the DESTINY+ Target Asteroid

Jooyeon Geem, Masateru Ishiguro, Jun Takahashi +23

We report on the first polarimetric study of (3200) Phaethon, the target of JAXA's DESTINY mission, in the negative branch to ensure its anhydrous nature and to derive an accur…

A rare phosphorus-rich star in an eclipsing binary from TESS

Colin P. Folsom, Mihkel Kama, Tõnis Eenmäe +6

Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative env…
