Table 5.
Grouping of the TDEs in our sample in four subcategories (two of the H+He type and two of the H type) based on their spectroscopic features at early times (pre-peak to a ∼month after peak).
| Type | H+He | H | ||
|---|---|---|---|---|
| subtype | Fe (+O) | N | DP | Plain |
| X-rays | 2/2 ( † ) | 1/6 ( * ) | 2/2 ( † ) | 0/2 |
| Potential | Small | Large | (Small to) | Intermediate |
| viewing angles | intermediate | (to large) | ||
Notes. ( * )ASASSN-14li is the only TDE of the H+He Nitrogen-rich subcategory that shows X-ray emission and in the same time has the lowest FWHM of all the TDEs in our sample. It is potentially viewed from an intermediate angle rather than a large one. ( † )PTF09ge which is the third event of the H+He Iron-rich subcategory as well as PTF09djl which is the third event of the H double-peaked subcategory, were not monitored by any X-ray telescope while they were bright in the optical hence they could potentially be bright in X-rays as well during that time.
