| Abstract: |
Radio follow-up observations of supernovae are crucial for understanding the radial profile of the circumstellar medium of the progenitor star and can shed light on the final evolutionary stage of massive stars. We conducted 6.8 and 8.4 GHz follow-up observations for SN 2023ixf, which was discovered as the closest type II supernova in decades, using the Japanese VLBI Network. We observed for 9 epochs between 1 and 108 days after discovery, providing an upper limit on the flux density at the mJy level if in good condition. The upper limits were used to constrain the mass-loss history of the progenitor star of SN 2023ixf. |
