Asteroseismic predictions for a massive main-sequence merger product (online data)

# Online data for "Asteroseismic predictions for a massive main-sequence merger product" (Henneco et al. 2025) This repository contains the in- and output files for the `MESA` and `GYRE` computations that are part of Henneco et al. (2025), as well as the online appendix with supplementary figures. ## Appendix **online_appendix.pdf** - PDF with the online appendix for the paper containing supplementary figures. ## MESA Data related to the `MESA` computations. **MESA version** MESA r12778 MESA SDK 20.3.2 ### INPUT `MESA` work directories for the merger product and genuine single star models. - **3dmhd_mesawork** - Work directory to relax the chemical and entropy profiles from the *3D MHD* merger product of Schneider et al. (2019) and evolve the resulting stellar structure. - **es_mesawork** - Work directory to relax the chemical profile resulting from *entropy sorting* and evolve the resulting stellar structure. A `Python` script with the entropy sorting routine and merger progenitor stellar structures can be found in `es_mesawork/initial_merger_models`. The latter were computed using the `merger_progenitor_mesawork` setup. - **pm_mesawork** - Work directory to relax the chemical and entropy profiles resulting from the `PyMMAMS` routine and evolve the resulting stellar structure. The `PyMMAMS` routine itself is not included in this repository, but will be made available as part of Heller et al. (in prep.). - **fa_mesawork** - Work directory to evolve a single star until a certain age and subsequently accrete a certain amount of mass in a specified fraction of the star's global thermal timescale (*fast accretion*). - **merger_progenitor_mesawork** - Work directory to create *single-star* merger progenitor structures used as input for the entropy sorting and `PyMMAMS` routines. `MESA` setup adapted from the one used to create the merger progenitor structures of the 3D MHD simulation of Schneider et al. (2019). - **gss_mesawork** - Work directory to evolve genuine single stars with a specified mass. ### OUTPUT History and profile output for the merger product and genuine single-star models. The `profileXX.data` files are those for the central hydrogen mass fractions specified in the paper: 0.60, 0.50, 0.40, 0.30, 0.20, 0.10, 0.01 (for the merger products, the central mass fractions for the genuine single stars differ slightly, see beginning of Sect. 4). The central mass fraction decreases with increasing profile numbers. #### genuine_single_stars - **mXY.Z** - `MESA` output for the genuine single star with an initial mass of XY.Z solar masses. #### merger_products - **3dmhd** - `MESA` output for the 3D MHD merger product. - **es** - `MESA` output for the entropy sorted merger product. - **pm** - `MESA` output for the `PyMMAMS` merger product. - **fa** - `MESA` output for the fast accretion merger product. ## GYRE In- and output files for the `GYRE` computations. **GYRE version** GYRE 7.0 MESA SDK 22.6.1 ### INPUT Templates for the `GYRE` computations. - **gyre_nonrot_template.in** - `GYRE` inlist for g modes without the effects of the Coriolis force. - **gyre_rot_template.in** - `GYRE` inlist for g modes with the effects of the Coriolis force under the Traditional Approximation of Rotation (TAR). - **gyre_nonrot_pmodes_template.in** - `GYRE` inlist for p modes without the effects of the Coriolis force. - **gyre_rot_pert_pmodes_template.in** - `GYRE` inlist for p modes with the effects of the Coriolis force through the first-order perturbative approach. ### OUTPUT `GYRE` summary files for the merger product and genuine single-star models. #### genuine_single_stars - **m16.9**, **m17.0**, **m17.15** - summary files for g modes (`gmodes`) and p modes (`pmodes`) without the effects of the Coriolis force for each of the profiles in the `MESA` output directories. - **m17.4** - summary files for g modes (`gmodes`) and p modes (`pmodes`) with (`_rot`) and without the effects of the Coriolis force for each of the profiles in the `MESA` output directories. #### merger_products - **es**, **pm**, **fa** - summary files for g modes (`gmodes`) and p modes (`pmodes`) without the effects of the Coriolis force for each of the profiles in the `MESA` output directories. - **3dmhd** - summary files for g modes (`gmodes`) and p modes (`pmodes`) with (`_rot`) and without the effects of the Coriolis force for each of the profiles in the `MESA` output directories.# 论文《主序星大质量并合产物的星震学预言》（Henneco等，2025）的在线数据集 本仓库包含Henneco等人（2025）研究中涉及的`MESA（Modules for Experiments in Stellar Astrophysics）`与`GYRE`计算所需的输入、输出文件，以及包含补充图表的在线附录。 ## 附录 **online_appendix.pdf**——内含论文在线附录的PDF文件，包含所有补充图表。 ## MESA（恒星天体物理实验模块） 与`MESA`计算相关的数据。 ### MESA版本 MESA r12778 MESA SDK 20.3.2 ### 输入文件 用于并合产物与真实单星模型的`MESA`工作目录。 - **3dmhd_mesawork**：用于松弛Schneider等人（2019）的三维磁流体动力学（3D MHD）并合产物的化学与熵分布，并演化所得恒星结构的工作目录。 - **es_mesawork**：用于松弛经熵排序得到的化学分布，并演化所得恒星结构的工作目录。熵排序程序与并合前身星恒星结构的Python脚本可在`es_mesawork/initial_merger_models`路径下获取，后者通过`merger_progenitor_mesawork`配置计算得到。 - **pm_mesawork**：用于松弛经`PyMMAMS`程序得到的化学与熵分布，并演化所得恒星结构的工作目录。本仓库未包含`PyMMAMS`程序本身，该程序将作为Heller等人（待发表）研究的一部分公开。 - **fa_mesawork**：用于将单星演化至指定年龄，随后在恒星整体热时标的指定比例内吸积指定质量的工作目录（即“快速吸积”）。 - **merger_progenitor_mesawork**：用于创建作为熵排序与`PyMMAMS`程序输入的单星并合前身星结构的工作目录。该`MESA`配置改编自Schneider等人（2019）三维磁流体动力学模拟中用于生成并合前身星结构的配置。 - **gss_mesawork**：用于演化指定初始质量的真实单星的工作目录。 ### 输出文件 并合产物与真实单星模型的演化历史与结构剖面输出文件。`profileXX.data`文件对应论文中指定的中心氢质量分数：0.60、0.50、0.40、0.30、0.20、0.10、0.01（对于并合产物，真实单星的中心质量分数略有差异，详见第4节开头）。中心氢质量分数随剖面编号增加而降低。 #### 真实单星 - **mXY.Z**：初始质量为XY.Z倍太阳质量的真实单星的`MESA`输出文件。 #### 并合产物 - **3dmhd**：三维磁流体动力学并合产物的`MESA`输出文件。 - **es**：经熵排序的并合产物的`MESA`输出文件。 - **pm**：经`PyMMAMS`程序处理的并合产物的`MESA`输出文件。 - **fa**：经快速吸积过程的并合产物的`MESA`输出文件。 ## GYRE（星震学计算软件） 用于`GYRE`计算的输入与输出文件。 ### GYRE版本 GYRE 7.0 MESA SDK 22.6.1 ### 输入文件 `GYRE`计算的输入模板。 - **gyre_nonrot_template.in**：无科里奥利力影响的g模式`GYRE`输入列表文件。 - **gyre_rot_template.in**：采用传统旋转近似（TAR）考虑科里奥利力影响的g模式`GYRE`输入列表文件。 - **gyre_nonrot_pmodes_template.in**：无科里奥利力影响的p模式`GYRE`输入列表文件。 - **gyre_rot_pert_pmodes_template.in**：采用一阶微扰方法考虑科里奥利力影响的p模式`GYRE`输入列表文件。 ### 输出文件 并合产物与真实单星模型的`GYRE`总结文件。 #### 真实单星 - **m16.9**、**m17.0**、**m17.15**：对应`MESA`输出目录中所有剖面的、无科里奥利力影响的g模式（`gmodes`）与p模式（`pmodes`）总结文件。 - **m17.4**：对应`MESA`输出目录中所有剖面的、考虑（后缀`_rot`）与不考虑科里奥利力影响的g模式与p模式总结文件。 #### 并合产物 - **es**、**pm**、**fa**：对应`MESA`输出目录中所有剖面的、无科里奥利力影响的g模式与p模式总结文件。 - **3dmhd**：对应`MESA`输出目录中所有剖面的、考虑（后缀`_rot`）与不考虑科里奥利力影响的g模式与p模式总结文件。
