Early emission characterization of TDE 2025aarm

In this work, we present early emission data analysis of the tidal disruption event TDE 2025aarm, including optical, UV, and X-ray data. At a redshift of z = 0.01368, TDE 2025aarm is the second closest TDE ever discovered, offering a valuable opportunity to study such phenomena in great detail. We observed TDE 2025aarm in the optical with the Liverpool Telescope for a total of three epochs. We complemented our dataset with ancillary spectroscopic and photometric data. The early optical spectra are characterized by a blue-continuum and helium, hydrogen, and possibly Bowen lines typical of H+He events. The optical light curves peak at M_g ∼ -18.68 mag and are well described by fallback of a M_⋆ ∼ 2 M_⊙ black hole. We report -XRT detection in the 0.3-10 keV range, with a total flux of F_ M_⊙ star onto a M_ ̊m BH 7 Swift X ∼ 1.42 ̊m,erg , -14 -2 ,s^ -1 , fit by a blackbody with k_BT ∼ 0.39 keV. This makes TDE 2025aarm a new event among optical/UV bright TDEs detected in soft X-rays. Our analysis suggests that the early emission from TDE 2025aarm is powered by circularization shocks and that the delayed accretion scenario best describes the observed features.
