A multi-technique detection of an eccentric giant planet around accelerating star HD 57625

D. Barbato, D. Mesa, V. D'Orazi +42

The synergy between different detection methods is a key asset in exoplanetology, allowing for both precise characterization of detected exoplanets and robust constraints even in t…

Spectropolarimetry of SN 2023ixf reveals both circumstellar material and helium core to be aspherical

Manisha Shrestha, Sabrina DeSoto, David J. Sand +33

We present multi-epoch optical spectropolarimetric and imaging polarimetric observations of the nearby Type II supernova (SN) 2023ixf discovered in M101 at a distance of 6.85 Mpc.…

Deepest limits on scattered light emission from the Epsilon Eridani inner debris disk with HST/STIS

Sai Krishanth P. M., Ewan S. Douglas, Ramya M. Anche +9

Epsilon Eridani ( Eri) is one of the first debris disk systems detected by the Infrared Astronomical Satellite (IRAS). However, the system has thus far eluded detection in scatt…

The space coronagraph optical bench (SCoOB): 3. Mueller matrix polarimetry of a coronagraphic exit pupil

Jaren N. Ashcraft, Ewan S. Douglas, Ramya M. Anche +4

High-contrast imaging in the next decade aims to image exoplanets at smaller angular separations and deeper contrasts than ever before. A problem that has recently garnered attenti…

Black Silicon BRDF and Polarization for Coronagraphic Pupil Masks

Emory L. Jenkins, Ramya M. Anche, Kyle J. Van Gorkom +2

Future space observatories will likely have segmented primaries, causing diffraction effects that reduce coronagraph performance. Reflective binary pupil apodizer masks can mitigat…

The Space Coronagraph Optical Bench (SCoOB): 5. End-to-end simulations of polarization aberrations

Ramya M Anche, Kyle J. Van Gorkom, Jaren N. Ashcraft +4

Polarization aberrations originating from the telescope and high-contrast imaging instrument optics introduce polarization-dependent speckles and associated errors in the image pla…

Unravelling the asphericities in the explosion and multi-faceted circumstellar matter of SN 2023ixf

Avinash Singh, R. S. Teja, T. J. Moriya +33

We present a detailed investigation of photometric, spectroscopic, and polarimetric observations of the Type II SN 2023ixf. Earlier studies have provided compelling evidence for a…

A Generalized Expression for Accelerating Beamlet Decomposition Simulations

Jaren N. Ashcraft, Ewan S. Douglas, Ramya Anche +7

Paraxial diffraction modeling based on the Fourier transform has seen widespread implementation for simulating the response of a diffraction-limited optical system. For systems whe…
