cds-question@unistra.frasteroseismologygiant-starsphotometryvisible-astronomyThe individual modes and asymptotic parameters are important characteristics of stellar oscillation. Using TESS 2 minute cadence data from Sectors 1 to 75, we perform asteroseismic analysis of 687 red giants, and provide their oscillation mode parameters. The mode parameters, including frequencies {nu}_n,l_, amplitudes A_n,l_, and line widths {Gamma}_n,l_, are obtained through Markov Chain Monte Carlo fitting. The median uncertainty for frequency is 0.047{mu}Hz. Using the radial mode frequencies, we calculate the values of {Delta}{nu}, and derive asymptotic parameters ({epsilon}p, {epsilon}c, {delta}{nu}0l, q, and {Delta}{Pi}1) based on l=0,1,2 modes. For red giants with {Delta}{nu}>15.6{mu}Hz, there is a weaker correlation between {delta}{nu}02 and {Delta}{nu}, and a stronger mass dependence, compared to stars with lower {Delta}{nu}. Additionally, the ratio {delta}{nu}02/{Delta}{nu} presents a pronounced increase with {Delta}{nu} decrease, as these stars undergo rapid core contraction and their convective envelopes extend deep into the interior. At this stage, the ratio {delta}{nu}02/{Delta}{nu} may serve as a robust indicator for diagnosing the location of the convective boundary. Furthermore, the {epsilon}c values can be a potential index to distinguish red clump (RC) and secondary RC stars from red giant branch stars in the TESS field.2025ApJS..279...37Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/279/37CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)J/A+A/540/A143 : Oscillations of red giants observed by Kepler (Mosser+, 2012)J/ApJ/765/L41 : Asteroseismic classification of KIC objects (Stello+, 2013)J/ApJS/210/1 : Asteroseismic study of solar-type stars (Chaplin+, 2014)J/ApJS/211/2 : Revised properties of Q1-16 Kepler targets (Huber+, 2014)J/ApJ/827/50 : Kepler faint red giants (Mathur+, 2016)J/AJ/152/158 : Final Kepler transiting planet search (DR25) (Twicken+, 2016)J/MNRAS/463/1297 : Asteroseismology of misclassified red giants (Yu+, 2016)J/ApJ/835/172 : Kepler asteroseismic LEGACY sample.
