Abstract
The Nuclear Energy Density Functionals (NEDF) are the appropriate, reliable, and successful tools to study the nuclear properties and excitations under extreme conditions. This research project will contribute to worldwide scientific efforts to better understand the structure of nuclei under extreme conditions, for instance, increasing nucleon number and temperature. Besides, the results of this work can make an important contribution to the astrophysical modelling of events occurring in stellar environments.

| Title | Drip lines at finite temperature |
| Description | The dataset contains the nuclear drip lines (limits of nuclear stability) at finite temperatures. Calculations are performed with 7 relativistic energy density functionals including DD-ME2, DD-PC1, DD-PCX, and those constrained to specific symmetry energy at saturation density, DD-PCJ30, DD-PCJ32, DD-PCJ34, and DD-PCJ36. The calculations are performed for temperatures T = 0, 0.5, 1, 1.5, and 2 MeV for all functionals, with additional points T = 0.8, 1.2, and 1.8 for DD-ME2, DD-PC1, and DD-PCX. The data is stored in 44 text (.txt) files corresponding to different functionals and temperatures. The name of each data file consists of two parts: (i) the functional used for calculation, and (ii) temperature. For instance, the file "DDME2_T15.txt" corresponds to calculations with DD-ME2 functional at T = 1.5 MeV (we removed the decimal point from the temperature to avoid confusion with the data format). The data consists of 4 columns, where the first column is the temperature (T) in MeV, the second is the proton number (Z), the third neutron number for the isotope at the proton drip line, and the fourth neutron number of the isotope at the neutron drip line. This information is written in the header of each file as: # Temp [MeV] Z(proton number) N(proton drip neutron number) N(neutron drip neutron number) Using the provided information one can easily plot the drip lines as a function of temperature for different functionals. |
