Sub 35-ps Single-Photon Stellar Intensity Interferometry of Vega

Verena G. Leopold, Sebastian Karl, Stefan Richter +7

SII enables measurements of stellar photospheres by correlating intensity fluctuations, offering a robust alternative to amplitude-based techniques. With the advent of modern singl…

Panchromatic JWST Observations and Models of the Dim Type Iax Supernova 2024vjm at 200 days

E Baron, J. M. DerKacy, C. Ashall +23

We report JWST spectra and photometry of the underluminous SN Iax 2024vjm obtained 202.8 restframe days post-explosion. The spectrum exhibits a rich set of forbidden lines from low…

Stellar physics at sub-nanoradian angular resolution

P. Batista, J. Biteau, C. Carlile +36

Many stars -- if they could be imaged with enough angular resolution -- would exhibit features expected from theory but not possible to extract from spectra. We may group these by…

Measurement of the photosphere oblateness of Cassiopeiae via Stellar Intensity Interferometry with the VERITAS Observatory

A. Archer, J. P. Aufdenberg, P. Bangale +58

We use the stellar intensity interferometry system implemented with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) at Fred Lawrence Whipple Observatory (FLWO…

The NewEra model grid

Peter H. Hauschildt, T. Barman, E. Baron +2

Analyses of stellar spectra, stellar populations, and transit light curves rely on grids of synthetic spectra and center-to-limb variations (limb darkening) from model stellar atmo…

An Angular Diameter Measurement of UMa via Stellar Intensity Interferometry with the VERITAS Observatory

A. Acharyya, J. P. Aufdenberg, P. Bangale +44

We use the VERITAS imaging air Cherenkov Telescope (IACT) array to obtain the first measured angular diameter of UMa at visual wavelengths using stellar intensity interferometr…
